`In response to #Taiwan media claims that the PLA had breached the median line between Taiwan and the Chinese mainland last week, @MFA_China pointed out that such a "line" does not exist and reiterated that Taiwan is an inalienable part of #China' https://t.co/xd5l4BYY5T pic.twitter.com/Ny481pNwD7

On January 4, China announced the expansion of flight route M503, which lies 7 km away from the median line between the Chinese mainland and Taiwan.

China never consulted Taiwan on the decision. https://t.co/vSwPJcCpft pic.twitter.com/gowNdB8t9m

CHINA has said it is ready to do "whatever it takes" to bring Taiwan to heel – while rejecting the concept of the so-called "median line" which serves as an unofficial maritime border between the island and the mainland. That's war talk! https://t.co/sET2lrufkv
