TAIPEI • Taiwan's air force scrambled yesterday to warn away 10 Chinese aircraft that entered its air defence zone, the island's defence ministry said, the day after the government announced a US$9 billion (S$12 billion) boost to military spending to counter the threat from China.

Chinese-claimed Taiwan has complained for a year or more of repeated missions by China's air force near the democratically governed island, often in the southwestern part of its air defence zone close to the Taiwan-controlled Pratas Islands.

The latest Chinese mission involved 6 J-16 and 2 J-11 fighters plus one anti-submarine and one reconnaissance aircraft, the Taiwan ministry said.

Taiwan sent combat aircraft to warn away the Chinese aircraft, while missile systems were deployed to monitor them, the ministry said.

The Chinese fighters flew in an area close to the Pratas, while the anti-submarine and reconnaissance aircraft flew into the Bashi Channel that separates Taiwan from the Philippines, according to a map that the ministry issued.

There was no immediate comment from China.

The incident came a day after Taiwan proposed extra defence spending of US$8.7 billion over the next five years, including on new missiles, warning of an urgent need to upgrade weapons in the face of a "severe threat" from China.

Speaking earlier yesterday, Taiwan Premier Su Tseng-chang said the government had to take the threat from China seriously.

Taiwan's defence spending "is based on safeguarding national sovereignty... and national security. We must not relax. We must have the best preparations so that no war will occur", he said.
