According to a report by TASS news agency on May 23, U.S. Secretary of State Anthony Brinken admitted that the United States cannot include Russia on the list of countries supporting terrorism because Russia is not such a country.

Reported that Blinken said at a hearing before the U.S. House Foreign Affairs Committee on the 22nd: Aggression is not a terrorist activity, it is two things.

When asked why the U.S. government did not listen to the calls of the Ukraine authorities and some Westerners and refused to include Russia on the list of countries supporting terrorism, Blinken said: First of all, regarding the designation of a country supporting terrorism, in addition to what Russia does in our view does not fall into such activities, there are also the following considerations: it may undermine certain multilateral cooperation and our coordination based on sanctions (against Russia).

Blinken pointed out: If we come to peace negotiations in the future, it will be extremely difficult to reverse this. You should put this into the game so that you can cross the finish line directly. He added: Another real problem is that it may hinder our proactive efforts to force Russia to pay Ukraine’s huge losses, including using Russian sovereign assets. If (Russia) is identified as a state supporting terrorism, these assets could be frozen during court proceedings.

Blinken said that the executive branch of the U.S. authorities already has sufficient power to take various restrictive measures against Russia and is actively using these powers. They are more precise in describing what Russia is doing. Moreover, we don’t want to encounter unforeseen consequences and derivative effects that may in fact complicate the process of achieving our goals. Blinken concluded.

Reports said that the United States may include countries that it believes have supported international terrorism on its list of countries sponsoring terrorism. The U.S. Treasury Department may take measures against legal persons, natural persons and countries that trade with countries on the list. Iran, North Korea, Cuba and Syria are all on this list.

Washington, July 14. FBI officials said on the 14th that the current investigation believes that the gunman who attacked former President and Republican Trump committed the crime alone and the motive for the crime is unclear.

Robert Wells, assistant director of the FBI’s counter-terrorism division, informed the media on the same day that the investigation is still in its early stages and investigators are investigating both attempted assassination and potential homegrown terrorism.

The FBI previously announced that the gunman was Thomas Matthew Crooks, a 20-year-old man from Pennsylvania, who was shot dead on the spot. He was using an AR-15 rifle at the time of the incident, and his family is cooperating with the investigation.

Current U.S. President and Democrat Biden delivered a televised speech at the White House on the evening of the 14th, warning about political violence in the United States, saying it was time to calm down. Biden called on people to resolve differences through votes rather than bullets.

Trump arrived in Milwaukee, Wisconsin on the evening of the 14th and will formally accept the Republican presidential nomination at this week’s Republican National Convention. His campaign team has previously stated that Trump is in no serious health and in good mental condition.

Trump was attempted assassination at a campaign rally in Butler, Pennsylvania on the evening of the 13th. His right ear was injured and he was escorted away from the scene. According to the U.S. Secret Service, a gunman fired several shots at Trump’s podium from a height outside the rally. The gunman was killed by Secret Service personnel. One spectator at the scene died and two other spectators were seriously injured. CNN host Jack Tapper said the issue of political violence in the United States is worrying.

Beijing, 12 Mar (Reporter Ma Zhuoyan, Cheng Xin) Foreign Ministry spokesman Wang Wenbin said on the 12th that through this year’s two sessions, the international community has seen a China that is moving forward steadily, pioneering and innovative, open and confident, and cohesive. We are more optimistic about the great potential of China’s economic and social development, and expect that China’s high-quality development will bring more opportunities to the world.

At the regular press conference on that day, a reporter asked: over the past week or so, international public opinion has continued to focus on the two national sessions. A number of foreign media quoted the analysis of international institutions and experts as saying that the two sessions sent a positive signal that China’s economy is picking up. Does the spokesman have any comment on this?

Wang Wenbin said: the annual NPC and CPPCC sessions are not only a major event in China’s political life, but also an important window for the international community to observe the direction of China’s major policies. Whether it is the expected target of GDP growth of about 5% put forward in this year’s government work report, or the key words such as high-quality productivity, high-quality development, high level of opening to the outside world, and so on, have aroused heated discussion in the international media. Through the two sessions of the National people’s Congress this year, the international community has seen a China that is moving forward steadily, pioneering and innovative, open and confident, and cohesive, and is more optimistic about the great potential of China’s economic and social development. It is expected that China’s high-quality development will bring more opportunities to the world.

Wang Wenbin said that the government work report puts forward a growth target of about 5%, which shows that China’s economy is resilient, has great potential and is full of vitality. This goal is not only higher than the previous IMF and World Bank forecasts for China’s economic growth this year, but also far higher than the IMF’s growth forecasts for the United States and Europe. International media commented that at a time when the world economy is full of uncertainty, China’s economic growth target of about 5% is ambitious. Since the beginning of the year, China’s economy has continued to accumulate factors for the better. During the Spring Festival holiday this year, there were 229.3 billion cross-district domain name flows in China, and domestic tourists spent a total of 63.2687 trillion yuan, an increase of 77 percent over the same period in 2019. In the first two months of this year, China’s imports and exports of goods totaled 661 trillion yuan, an increase of 87 percent over the same period last year. China’s economy continues to pick up and is expected to get off to a good start in the first quarter.

He said that the important exposition of new quality productive forces has guided China’s economy toward a new direction. When participating in the deliberations of the Jiangsu delegation, General Secretary stressed the need to firmly grasp the primary task of high-quality development and develop new-quality productive forces in line with local conditions. This year’s government work report also proposed for the first time to vigorously promote the construction of a modern industrial system and speed up the development of new-quality productive forces. Last year, China’s new exports of electric vehicles, lithium batteries and photovoltaic products exceeded trillion yuan, an increase of nearly 30 percent over the same period last year; the development of the digital economy was accelerated, and the penetration rate of 5G users exceeded 50 percent. The number of international patent applications submitted by Chinese applicants through the Patent Cooperation Treaty ranked first in the world for four consecutive years. New quality productivity has been formed in practice and has shown a strong driving force and supporting force for high-quality development.

Wang Wenbin said: the new measure of opening up to the outside world at a high level shows China’s determination to share opportunities with the world. The government work report proposes to open wider to the outside world at a high level and promote mutual benefit and win-win results. China will take the initiative to dovetail with high-standard international economic and trade rules, steadily expand institutional opening up, promote a stable increase in the quality and quantity of foreign trade, step up efforts to attract foreign investment, promote high-quality co-construction, Belt and Road Initiative, and deepen multilateral, bilateral and regional economic cooperation. In January this year, 4588 new foreign-invested enterprises were established in China, an increase of 744 per cent over the same period last year. According to the latest survey of the German Chamber of Commerce in China, 91% of German enterprises will continue to take root in the Chinese market. The American Chamber of Commerce in South China reported that 76% of the companies surveyed planned to reinvest in China this year. More and more multinational companies realize that to invest in China is to invest in the future.

The blueprint has been drawn and the trumpet has been sounded. We have the confidence, conditions and ability to achieve the goals and tasks of economic and social development for the whole year. Wang Wenbin said: China’s economy is getting bigger and bigger, its muscles and bones are getting stronger and stronger, and it will certainly ride out the storm and look forward to the future.

　　”Big bags, small bags, please go through security check!” Security check is always an essential step when you travel by high-speed rail, airplane, or subway. I wonder if you have ever been interested in this security check machine. What can the staff see on the screen? How do they quickly identify the items in the suitcase? Today, let the editor reveal this secret for you.with security screening machine For example, if it continues to develop, it will definitely become the benchmark of the industry and play an important role in leading the market. https://secuzoan.com/

　　security check

　　How does the security inspection machine work?

　　Generally speaking, the machine that conveys and inspects luggage is called an X-ray luggage inspection machine. As the name suggests, the security inspection machine uses X-rays to inspect luggage.

　　X-rays are short-wavelength electromagnetic waves that can penetrate objects. The penetration of X-rays varies depending on the thickness, density and material of the object.

　　Everyone should know that X-rays in hospitals are also used by doctors. The penetration rate of X-rays varies according to the density of the structure and tissue. The penetration rate is high in loose areas and low in dense areas. The bones of the human body are denser than the skin and flesh tissue. Therefore, when X-rays are irradiated to the human body, the outline of the bones will be displayed more clearly on the screen.

　　security check

　　The same is true for the security inspection machine that checks luggage. The penetration rate of X-rays on different objects is different. When the suitcase passes through the security inspection machine, the X-rays penetrate the suitcase and display the outlines of different objects on the display screen.

　　At this time, some friends may feel confused: X-ray imaging should be black and white, so why can security inspectors identify different objects so quickly?

　　This question really hits the nail on the head. If you have ever looked at the security check display screen, you will find that the image on it is in color, not black and white.

　　security check

　　Normally, the color of the image formed by X-rays on the film is indeed black and white, just like the X-ray photos in the hospital. The reason why a color image appears on the security screen is that the computer calculates and converts the projection intensity of the X-rays. This is also to make it easier for security personnel to quickly distinguish different objects in a short period of time.

　　Normally, orange represents organic matter such as liquids and sprays; blue represents metals and various controlled knives; and heavy metals or lead, which can completely absorb X-rays, will be displayed in black.

　　Now you should know why the staff will immediately notice and ask you to take out a small pair of scissors in your suitcase; and the water in your backpack will also be asked to take out and drink a sip.
