A deputy head of the Chinese Cabinet's Taiwan Affairs Office has been placed under investigation for apparent corruption amid renewed scrutiny on Beijing's policies toward the island.

A brief statement from the ruling Communist Party's Central Commission for Discipline Inspection said in a brief statement that Gong was suspected of "serious violations of discipline," which is usually a euphemism for graft. No other details were given.

The announcement dated Tuesday came three days after Taiwanese voters elected an independence-leaning president in a landslide, although there was no indication of a direct connection between the two events.

President Xi Jinping is believed to be deeply unsatisfied with the office's failure to obtain results in Beijing's quest to win over Taiwanese to China's goal of political unification.
