Taiwan's defense ministry reported that Chinese military airplanes—including nuclear-capable bombers—flew into the nation's air defense identification zone on Sunday. China claims Taiwan under its "one country, two systems" policy, but democratically run Taiwan functions independently of the mainland and tensions have been high for decades. However they have increased over the past year as Taiwan has complained about repeated incursions of its airspace by Chinese military planes.
On Sunday, Taiwan's air force scrambled against 19 Chinese military aircraft, Reuters first reported. Taiwan's defense ministry said that the incursion included 10 J-16 and four Su-30 fighters. Additionally, China sent four H-6 bombers, which can transport nuclear weapons, as well as an anti-submarine aircraft.
