  The US Department of State has urged China and Taiwan to enter into dialogue to resolve flight route disputes across the Taiwan Strait after Beijing announced its unilateral decision to launch the W121 flight route over the weekend.

  In a reply to CNA's inquiry, a US State Department spokesperson said Sunday that the US expected cross-Taiwan Strait differences to be resolved "by peaceful means, free from coercion, in a manner acceptable to the people on both sides of the Strait."

  The spokesperson said that the US stance related to cross-strait disputes was consistent.

  "Issues related to civil aviation and safety in the Taiwan Strait should be decided through dialogue between both sides," the spokesperson said.

  The statement from the US State Department was a response to China's unilateral announcement earlier Sunday that it would open the northwest-to-southeast W121 route connecting Dongshan in Zhejiang province to the north-south M503 flight route.

  It was not the first time Beijing has acted unilaterally on establishing flight routes.

  China moved the M503 route eastwards and closer to the median line of the Taiwan Strait in February last year, despite protests from Taiwan.

  The M503 route, unilaterally declared by China in 2015, is located in the Shanghai Flight Information Region but very close to the Taipei Flight Information Region, raising concerns about flight safety and Taiwan's sovereignty.

  After negotiations with Taiwan, when it was still governed by a Kuomintang (KMT) administration that favored better cross-Strait relations, China agreed to move the M503 route six nautical miles to the west of its original path.

  However, Beijing announced on Jan. 30 last year that it was shifting the route eastward again, effective Feb. 1.

  The opening of the W121 flight route comes after W122 and W123, two other west-to-east flight paths to the south of W121, were opened last year at the same time as the M503 route was moved eastward.

  Michael Mazza, senior director for research of the Institute for Indo-Pacific Security, told CNA yesterday that the unilateral openings of the flight routes represented both symbolic and substantive actions from China.

  In a symbolic way, Mazza said China wanted to use the launches to demonstrate sovereignty over the skies, hoping to make Taiwan feel isolated, as the International Civil Aviation Organization (ICAO) would not object.

  Substantively, Mazza said, these routes posed a national security concern to Taiwan as they allow Chinese pilots who might be involved in future military action against Taiwan to familiarize themselves with routes over the Taiwan Strait.

  He said China may use these routes to approach Taiwanese airspace without raising alarms by disguising military aircraft as civilian carriers.

  "Overall, China's air route machinations are part and parcel of a broader effort to pressure, envelop and complicate the defense of Taiwan," Mazza said.
