China reportedly tested a high -speed missile earlier, and US President Biden expressed concerns on Wednesday.

The Financial Times quoted a number of sources last week that China fired this hypersonic missile with a nuclear warhead in August.The missiles flew to the target after a circle around the earth, showing the advanced ability that made US officials unexpectedly.

Bynden visited Pennsylvania on Wednesday and was asked by reporters when he was worried about whether Chinese tested hypersonic missiles, "Yes".

The White House spokesman Puski told reporters that this concern has been expressed through the "Diplomatic Channels".

According to the official website of the Ministry of Foreign Affairs of China, Chinese Foreign Ministry spokesman Zhao Lijian stated at a regular press conference on Monday that the test was a routine aerospace test to verify that the spacecraft can reuse technology.

Zhao Lijian also said: "This is of great significance to reduce the cost of use of spacecraft. It can provide convenient and cheap round -trip methods for human beings to use space to use space. Many companies in the world have conducted similar tests."

It is reported that China, the United States and Russia are currently developing hypersonic weapons.The speed of this type of weapon is five times the speed of sound. It does not have to fly along the fixed trajectory like a ballistic missile. It is more mobility and it is more difficult to track and intercept.

Study the Chinese nuclear military policy, but Taylor Fravel, an expert who did not know the test, said that China may bypass the US missile defense system mainly through the high supersonic gliding device equipped with nuclear warheadsEssence

Financial Times quoted earlier sources revealed that theoretically, this new weapon can fly over the Antarctic.This will make a huge challenge to the U.S. military because its missile defense system is concentrated on the Arctic route.

Four Tailin believes that if China completes and deploy this missile, this will "destroy stability."But he pointed out that the test does not mean that there are plans to deploy such weapons in China.
