BEIJING: Chinese officials trying to hide dishonest spending with tricks such as throwing extravagant parties in private will be targeted in a sustained campaign to root out hedonism, the top anti-graft watchdog said on Monday. Concealing spending by holding lavish dinners in private homes, passing off pampering at a spa as ?recuperation? from work and going sightseeing while on business trips are all in the sights of the graft busters. President Xi Jinping has waged a five-year war on graft at all levels of the ruling Communist Party, from high-level ?tigers? to lowly ?flies? and has pledged to keep up the fight until officials dare not, cannot and do not want to be corrupt.
