China has vowed to unify with Taiwan, which it considers its territory, though the Chinese Communist Party has never ruled there. Beijing, in recent years, ramped up military activitiesaround Taiwan to punish the island's Beijing-skeptic ruling Democratic Progressive Party.

U.S. Secretary of State Marco Rubio and others in President Donald Trump's administration have stressed deterring China means making an invasion as costly as possible.
