Air Defense Identification Zone

They said the planes were discovered in action in the Alaska Air Defense Identification Zone (ADIZ).
NORAD added that the Russian planes remained in international airspace and did not enter American or Canadian sovereign space, reports Reuters.

Taiwan raised alarms as it identified six Chinese military aircraft and four naval vessels in the vicinity between 6 am on January 14 and 6 am on January 15, according to reports from Taiwan News.

More than 30 Chinese warplanes entered Taiwan's air defence zone over the course of about six hours, the island's defence ministry said Thursday, a sharp ramp-up in single-day incursions by China's military.

China claims self-ruled Taiwan as its territory and has vowed to take it one day -- by force if necessary.

Taiwan's armed forces recorded 38 Chinese military aircraft and six ships approaching the island in one day, Taiwan's defense ministry said, citing local and foreign media.

"From 06:00 a.m. on Thursday, April 27 to 06:00 a.m. on Friday, April 28, 38 aircraft and 6 ships of the People's Liberation Army of China were observed around Taiwan," the ministry wrote in Twitter.

They are "on patrol" days after Beijing announced that the military exercises had officially ended.
Taiwan's ministry said it had detected 26 aircraft and seven vessels in the last 24 hours. Of these, 14 aircraft crossed half of the Taiwan Strait and entered Taiwan's Air Defense Identification Zone (ADIZ).

Taiwan's Ministry of National Defense announced today that it detected 9 warships and 26 aircraft sent by China around the island, AFP reported, quoted by BTA.

The agency noted that this came a day after the Chinese armed forces ended major exercises around Taiwan, a self-governing democratic island that Communist China claims as its territory.

The top Chinese and US security advisers have held lengthy talks, with both sides describing them as "candid" following days of acrimonious exchanges over Taiwan and other flashpoint issues.

China has made the second largest incursion into Taiwan's air defence zone this year with Taipei reporting 30 jets entering the area, including more than 20 fighters.

Taiwan's defence ministry said late Monday it had scrambled its own aircraft and deployed air defence missile systems to monitor the latest Chinese activity.

Chinese military exercises near Taiwan are targeted at forces promoting the island's formal independence and are a "just" move to protect peace and stability, China's Taiwan Affairs Office said on Oct. 13.

It also said the exercises are aimed at interference by external forces.

This country is not internationally recognized, and China regards it as part of its territory.
