Taiwan’s defence ministry said a total of 21 Chinese combat planes – 17 Chengdu J-10 multirole fighters and four advanced Shenyang J-16 strike fighters – had flown into the southwestern corner of the island’s air defence identification zone (ADIZ) on Thursday.
The J-10s, an older fighter model that first entered service 20 years ago, flew closer to the Chinese coast than Taiwan’s, while the J-16s, a much newer and more advanced fighter, flew in an area to the northeast of the Taiwan-controlled Pratas Islands, according to a map of the incident released by the ministry.
A further eight Chinese aircraft and four Chinese naval vessels were also detected operating off the coast of Taiwan but did not enter the ADIZ, the ministry said.
Taiwan’s armed forces were monitoring “the situation and tasked CAP [combat air patrol] aircraft, Navy vessels, and land-based missile systems to respond to these activities,” the defence ministry said in its statement.
On Wednesday, Taiwan reported that 19 Chinese air force combat planes had entered the air defence zone in the previous 24 hours.
Washington’s announcement of the potential sale of almost $620 in hi-tech arms to Taiwan is likely to further heighten tensions between the US and Beijing.
The Pentagon said on Wednesday that the US State Department had approved the potential sale to Taiwan of arms and equipment including 200 anti-aircraft Advanced Medium-Range Air-to-Air Missiles (AMRAAM) and 100 AGM-88B HARM missiles that can take out land-based radar stations.
“The proposed sale of this equipment and support will not alter the basic military balance in the region,” Taiwan’s defence department said in a statement.
The weapons sale will “contribute to the recipient’s capability to provide for the defence of its airspace, regional security, and interoperability with the United States,” it added.
Taiwan’s defence ministry said the missiles would help “effectively defend the airspace to deal with threats and provocations from the Communist military” and would bolster defence stockpiles.
Raytheon Technologies and Lockheed Martin are the principal contractors, it added. China has sanctioned both companies for selling Taiwan weapons.
Taiwan has complained for years of stepped-up Chinese military activities near the island as Beijing seeks to assert its claims over the democratically-run Taiwan. China maintains its activities are justified as it seeks to defend its territorial integrity and has warned the US against “colluding” with Taiwan.
