China's foreign exchange reserves edged down to $3.1332 trillion by the end of February due to a strong dollar and a fall in global financial markets, the State Administration of Foreign Exchange said on Tuesday.

This was a decline of $51.3 billion or 1.61 percent compared with the end of January, SAFE said in a statement.

The country's foreign exchange reserves dipped as global financial markets shed while the dollar strengthened, driven by macroeconomic data and anticipations of policy adjustments by major central banks.

A strengthening dollar makes reserves denominated in other currencies less valued in dollar terms.
