The State Department downgraded its travel advisory for China on Wednesday after the release of three U.S. citizens who had been held in the country for years.

The State Department on Wednesday downgraded its travel advisory for China, shortly after the White House announced it had secured the release of three Americans as part of a prisoner swap with Beijing.

The White House on Wednesday announced that China released Mark Swidan, Kai Li and John Leung. Swidan and Li were considered wrongfully detained. China also released an American pastor earlier this year.

The exchange, in which three Americans were freed Wednesday, played a role in the State Department’s downgrading of the travel advisory for China.
