Comprehensive Agreement on Investment

The Comprehensive Agreement on Investment (CAI) is a proposed investment deal between the People's Republic of China and the European Union. Proposed in 2013, the deal has not been signed as of 5 April 2024. In December 2020, the European Commission announced that the agreement was concluded in principle by the leaders of the European Council, pending ratification by the European Parliament.

In March 2021, it was reported that there would be serious doubts about the approval of the deal in the European Parliament given China's "unacceptable" behavior toward members of the parliament, the European Council's Political and Security Committee, and European think tanks.
