The end of 2017 and the first weeks of the new year saw several notable developments involving cross-strait relations. In late December and early January, in an alarming new practice, People’s Liberation Army bombers several times conducted reconnaissance flights that circumnavigated Taiwan. On Jan. 4, the People’s Republic of China (PRC) also unilaterally announced a new northbound flight path for its civilian aircraft (the M503 route) along the middle of the Taiwan Strait that violated a longstanding practice to keep such aircraft away from the centerline of this sensitive body of water.
