China's Communist Party must "turn the knife inward" to eliminate problems of discipline, including corruption, President Xi Jinping said, a new call to hunt down corrupt officials and those who corrupt them.

President-elect Donald Trump has invited Chinese President Xi Jinping to his inauguration in January, though it's unclear whether he plans to attend. In an interview Thursday on Fox News' "Fox and Friends," incoming White House press secretary Karoline Leavitt confirmed the invitation had been extended to Xi.

Chinese President Xi Jinping dismissed internal divisions within the ruling Communist Party as unavoidable, while calling for greater efforts to instill discipline, according to newly disclosed remarks he made at an anti-graft meeting in January.
