The United States and China have signed a brand-new, five-year agreement that dictates how the nations will cooperate on science and technology research. The pact is narrower in scope than its predecessor, covering only collaboration on basic science projects between departments and agencies of the two governments and excluding work on ‘critical and emerging technologies’ potentially important to national security, such as artificial intelligence and semiconductors. Unlike its predecessor, the pact does not include any information about collaboration among Chinese and US universities and private companies.
