China's forex reserves stood at $875.1 billion at the end of March, the last month for which official figures are available.

The reserves have surged in the past few years as the central bank buys most of the dollars generated by China's balance of payments surplus.

Reserves stood at $895 billion at the end of April, China Business News said.

Earlier this month, a senior government official said that China's growing trade surplus had boosted reserves to over $900 billion, forcing the government to turn its attention to tightening liquidity.
