(Beijing News) The US media quoted people familiar with the matter and revealed that China has recently increased its efforts to restrict overseas institutions' visits to China database. To a certain extent, some US think tank reports refer to China's sensitive practices, which has caused official vigilance.

In addition, the testimony of a senior researcher at the New American Safety Center in 2019 also made the testimony of the Chinese Economic and Security Review Committee, which also disturbed the Chinese leadership.That document implies that the Chinese military is actively exploring the use of artificial intelligence to enhance its combat effectiveness.The New American Security Center was created by Campbell, a coordinator of Indo -Pacific Affairs of the United States National Security Commission.

Some Chinese officials say that a think tank headquartered in Washington has the correct policy of adopting a tough policy for the United States to adopt a tough policy for China by digging the open source data of China.
