China has cut its holdings of U.S. Treasuries this month to raise dollars needed to support the yuan in the wake of a shock devaluation two weeks ago, according to people familiar with the matter.

Channels for such transactions include China selling directly, as well as through agents in Belgium and Switzerland, said one of the people, who declined to be identified as the information isn’t public. China has communicated with U.S. authorities about the sales, said another person. They didn’t reveal the size of the disposals.

The latest available Treasury data and estimates by strategists suggest that China controls $1.48 trillion of U.S. government debt, according to data compiled by Bloomberg. That includes about $200 billion held through Belgium, which Nomura Holdings Inc. says is home to Chinese custodial accounts.
