Laut Japan verletzte erstmals ein chinesisches Militärflugzeug seinen Luftraum

The violation of [Japan](https://www.nbcnews.com/news/world/us-japan-announce-historic-upgrade-security-ties-china-threat-looms-rcna147133)’s airspace by a Chinese military plane is “completely unacceptable,” the [Japanese government’s ](https://www.nbcnews.com/news/world/countering-china-us-sees-growing-role-japan-rcna143334)top spokesperson said Tuesday, a day after the U.S. ally scrambled its military in response to what it said was an unprecedented incursion.

While Beijing said it has no intention of violating any country’s airspace, China’s military assertiveness in the [Asia-Pacific, where it has vast territorial claims](https://www.nbcnews.com/news/world/china-new-map-anger-india-south-china-sea-border-disputes-rcna102921), has been a growing source of concern for the United States as well as China’s neighbors in the region, with confrontations becoming more common.

A Chinese military Y-9 intelligence-gathering aircraft entered Japanese airspace in the territorial waters off the Danjo Islands southwest of Japan’s main southern island of Kyushu from about 11:29 to 11:31 a.m. on Monday (10:29 to 10:31 p.m. Sunday ET), Chief Cabinet Secretary Yoshimasa Hayashi said, prompting Japan’s Air Self-Defense Force to warn it away.
