China's foreign exchange reserves increased to $3.209 trillion as of the end of January, up 0.21 percent or $6.7 billion from the previous month, official data showed on Friday.

The State Administration of Foreign Exchange said the country's foreign exchange reserves rose last month amid a declining US dollar index and rising global financial markets.

Meanwhile, China's official gold reserves came in at 73.45 million ounces at the end of January, up from 73.29 million ounces a month earlier, marking the third consecutive month of increase, according to SAFE.

The administration added that China's improving economic fundamentals will help its foreign exchange reserves stay generally stable going forward.
