China making more moves toward unification with Taiwan
Last week China flew a bunch of war jets over Taiwan.
Xi made new comments China would unify with Taiwan, the day before Taiwan's national day. In the past, Xi has threatened he might take Taiwan by force, but the recent statements were considered to be much softer than that.
One way to view Taiwan is as another province like those that have already been returned to China (Hong Kong and Macao in the 90s). A breakaway province.
