TAIPEI (REUTERS) - Taiwan's air force scrambled jets for a second consecutive day on Saturday (Sept 19) as multiple Chinese aircraft approached the island and crossed the sensitive midline of the Taiwan Strait, with the island's government urging Beijing to "pull back from the edge."

Taiwan's Defence Ministry said 19 Chinese aircraft were involved, one more than in the previous day, with some crossing the Taiwan Strait midline and others flying into Taiwan's air defence identification zone off its south-west coast.

It said China, which claims democratic Taiwan as its own territory, sent 12 J-16 fighters, two J-10 fighters, two J-11 fighters, two H-6 bombers and one Y-8 anti-submarine aircraft.

According to a map the ministry provided, none got close to mainland Taiwan itself or flew over it.

"ROCAF scrambled fighters, and deployed air defence missile system to monitor the activities," the ministry said in a tweet, referring to the Republic of China Air Force, the formal name of Taiwan's air force.

China had on Friday announced combat drills near the Taiwan Strait and denounced what it called collusion between the island and the United States.

US Undersecretary for Economic Affairs Keith Krach arrived in Taipei on Thursday for a three-day visit, the most senior State Department official to come to Taiwan in four decades, angering China.

Taiwan's Defence Ministry, in a separate statement, said China was carrying out provocative activities, seriously damaging peace and stability.

"The Defence Ministry sternly condemns this, and calls on the mainland authorities to control themselves and pull back from the edge."

China's widely read state-backed tabloid the Global Times, published by the ruling Communist Party's official People's Daily, said in a Saturday editorial that Friday's drills were a rehearsal to take over Taiwan.

"The US and Taiwan must not misjudge the situation, or believe the exercise is a bluff. Should they continue to make provocations, a war will inevitably break out," it said.

Both sides need to resume dialogue to reduce the risk of war, Mr Johnny Chiang, leader of Taiwan's main opposition party the Kuomintang, wrote on his Facebook page.

"People who are willing to play a communication role are stigmatised and people who clamour for war are regarded as heroes. Such an atmosphere is definitely not conducive to the peaceful and stable development of the Taiwan Strait," said Mr Chiang, whose party traditional favours close ties with China.

Life has continued as normal in Taiwan with no sign of panic.

The island has long been accustomed to living with Chinese threats. Taiwan's people have shown no interest in being ruled by China, re-electing President Tsai Ing-wen in a landslide last year on what was largely a platform of standing up to Beijing.

The latest Chinese flights came the same day Taiwan held a memorial service for former president Lee Teng-hui, dubbed "Mr Democracy" for ending autocratic rule in favour of free elections and championing Taiwan's separate identity from China.

Mr Lee, who died in July, became Taiwan's first democratically elected president in March 1996 after eight months of intimidating war games and missile tests by China in waters around the island.

Those events brought China and Taiwan to the verge of conflict, prompting the United States to send an aircraft carrier task force to the area in a warning to Beijing's government.
