Taipei angered at China's 'unilateral' change to Taiwan Strait flight path

TAIPEI - Taiwan’s government has expressed anger after China “unilaterally” changed a flight path close to the sensitive median line in the Taiwan Strait, saying it appeared to be a deliberate attempt to change the status quo for possible military means.

China’s civil aviation administration said in a short statement late on Jan 30 that from Feb 1, it was cancelling an “offset measure” for the south-bound operation of the M503 flight route, which is just west of the strait’s median line.

The median line had for years served as an unofficial barrier between Chinese-claimed Taiwan and China, but China says it does not recognise its existence and Chinese warplanes now regularly fly over it as Beijing seeks to pressure Taipei to accept its sovereignty claims.

China also said it was opening routes from west to east – in other words, in the direction of Taiwan – on two flight paths from China’s Xiamen and Fuzhou cities, which are close to the Taiwanese-controlled island groups of Kinmen and Matsu.

Taiwan’s civil aviation administration and China-policy making Mainland Affairs Council both labelled the moves as “unilateral” and that they strongly protested it.

The Mainland Affairs Council said China was ignoring flight safety, disrespecting Taiwan, and trying to “package” civil aviation for political or military considerations to potentially change the status quo in the strait.

“If the mainland side clings obstinately to its course, it must bear any serious consequences affecting cross-strait relations,” it said.

Chieh Chung, a military researcher at Taiwan’s National Policy Foundation, said the new route would be about 7km from the median line, which would squeeze the pre-warning and reaction time for Taiwan’s air defences.

“It is trying to completely eliminate and deny the existence of the median line,” he said.

China’s Taiwan Affairs Office described the changes as “routine” and to help alleviate pressure on airspace.

“It is also conducive to improving cross-strait flight operations and further facilitating cross-strait people-to-people exchanges, which are in line with the common interests of compatriots on both sides of the strait,” it said in a statement.

The M503 route is mostly used by Chinese airlines and also by foreign airlines going to and from cities like Shanghai to South-east Asia.

Flights to and from Taiwan and China’s Xiamen and Fuzhou take a circuitous route avoiding the median line, rather than flying directly across the strait.

Taiwan has complained about the M503 route before in 2018, when it said China opened the northbound part of it without first informing Taipei in contravention of a 2015 deal to first discuss such flight paths.
