BEIJING, Oct. 15 (Xinhua) -- China's fight against corruption has achieved an overwhelming victory and this momentum has been consolidated across the board, but the situation is still grave and complex, a spokesperson for the 20th National Congress of the Communist Party of China said here on Saturday.

The country will next focus on key areas and sectors, take firm action to "take out tigers," "swat flies," and "hunt down foxes," in order to win the critical battle against corruption, spokesperson Sun Yeli said at a press conference one day ahead of the congress.
