BEIJING, April 30 (Reuters) - China will step up its support for the economy, flexibly using policy tools, including banks' reserve requirement ratio (RRR) and interest rates, the Politburo, a top decision-making body of the ruling Communist Party, was quoted by state media as saying on Tuesday.

China will continue to implement a prudent monetary policy and proactive fiscal policy, the official Xinhua news agency cited the Politburo as saying, after a meeting chaired by President Xi Jinping.

China will actively expand domestic demand as the economic recovery still faces challenges, Xinhua quoted the Politburo as saying. (Reporting by Beijing Newsroom; Editing by Himani Sarkar)
