China’s foreign-exchange reserves declined in June as a strengthening U.S. dollar pressured the yuan. Reserves fell $9.68 billion to $3.222 trillion, or by 0.3%, by the end of the month, the State Administration of Foreign Exchange said Sunday.

Exchange-rate conversion and changes in asset prices contributed to the decline, the agency said.

Separately, China’s central bank last month halted purchases of gold purchases for a second straight month amid rising prices. The People’s Bank of China held 72.8 million troy ounces at the end of June, unchanged from a month earlier.
