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