The following is the May 19, 2026, Congressional Research Service in focus report, China: Nuclear and Missile Proliferation.
From the Report
The U.S. government for decades has expressed concerns about China’s proliferation of nuclear- and missile-related technologies to other countries, with recent focus on the threat of Chinese acquisition of U.S.-origin nuclear technology. (See CRS In Focus IF11050, New U.S. Policy Regarding Nuclear Exports to China.) Official U.S. government sources indicate that the Chinese government has ended its direct involvement in the transfer of nuclear- and missile-related items, but China-based companies and individuals continue to export goods relevant to those items, particularly to Iran and North Korea. U.S. officials also have raised concerns about entities operating in China that provide other forms of support for proliferation-sensitive activities, such as illicit finance and money laundering.
