China's foreign exchange reserves shrank by 0.24 percent to $3.214 trillion at the end of June, down $7.8 billion from a month earlier, official data showed Wednesday.

"The forex market has maintained stable operation, with rational and orderly transactions," deputy head of the State Administration of Foreign Exchange Wang Chunying said, commenting on the data. 

Wang attributed the fall to the weakening of major non-dollar currencies with the rollout of COVID-19 vaccines, pushing down the value of China's non-dollar assets. 

Although there are still uncertainties in the global economic and financial situation, China's economy has sustained a stable recovery, which will help to keep the forex reserves basically stable, according to Wang.
