Nineteen Chinese military jets, including nuclear-capable bombers, have entered Taiwan airspace, says the Taiwan air force.

On Sunday, Taiwan’s defence ministry reported that 19 Chinese fighter jets flew entered its airspace.

According to Reuters, there was no immediate comment from China.

According to a map provided by Taiwan’s defence ministry, the Chinese fighter jets “flew in an area closer to the Chinese than the Taiwanese coast.”

The country has been railing against China’s military activities close to its airspace for over a year, around its Pratas Islands.

Taiwan’s defence stated that the Chinese military planes included 10 J-16, four Su-30 fighters, four H-6 bombers, and an anti-submarine aircraft.

Following the incursion of the Chines aircraft into its airspace, Taiwan dispatched its combat aircraft and deployed its missile systems to monitor Chinese fighter jets.

On June 15, China launched 28 military aircraft near Taiwan’s airspace, the largest incursion to date.

Reuters reported that China often mounted “such missions to express displeasure at something Taiwan has done or at shows of international support for the democratically ruled island, especially by the United States, Taiwan’s main arms provider.”

A U.S. warship and Coast Guard cutter sailing through the Taiwan Strait late last month might have prompted China’s latest military activity.

Taiwan’s defence ministry raised the alarm last week that China’s threat was growing and could “paralyse” its defences.
