China on Thursday vowed to boost domestic consumption next year, state media said, as leaders concluded a key economic policy meeting.

Top leaders at the Central Economic Work Conference (CEWC), including President Xi Jinping, pledged to implement a "moderately loose" monetary policy, increase social financing and reduce interest rates "at the right time", according to state broadcaster CCTV.

Senior policymakers also laid out several "key tasks" to be carried out next year, including "vigorously" boosting consumption, stabilising foreign trade and halting the real estate market's fall.

"The adverse impact brought by changes in the external environment has deepened," CCTV said following the closed-door CEWC, adding however that the upward trend of China’s economy remains unchanged.

A separate readout from state news agency Xinhua, meanwhile, kept a pledge to "maintain the basic stability of the exchange rate at a reasonable and balanced level".
