China ended a major economic meeting on Wednesday, vowing to boost imports, open its markets and clean up noxious pollution.

The pledges were made at the annual Central Economic Work Conference, at which leaders review past policy and plan for the upcoming year.

The results of the three-day closed-door meeting were released by state news agency Xinhua. 

This year's meeting was set to focus on implementing the new economic direction President Xi Jinping outlined to the party congress in October, when he declared that China must shift from high-growth to high-quality development.

Xinhua's reports on this week's meeting made no mention of an official growth target for the year.
