China's President Xi Jinping condemned "cliques," "conspiracies" and "fraud" within upper echelons of the Communist Party and said there were urgent problems to be addressed, state media reported Wednesday.

Xi is nearly four years into an unprecedented crackdown on corruption which he has said threatens the party's survival. His campaign has brought down scores of senior officials in the party, the government, the military and state-owned enterprises.

"Political life in the party has been good in general terms, but there are also prominent problems which remain in urgent need of addressing," the official Xinhua news agency cited Xi as saying in a speech at the meeting.
