As reported earlier, China lobbed its diplomatic reaction to Trump's Sunday interview, in which the President-elect hinted he would use the "One China" policy as a bargaining chip in negotiations with China to extract futures trade concessions.
The Chinese H-6 bomber flew along the disputed "Nine-Dash line" Thursday, which surrounds the South China Sea and dozens of disputed Chinese islands, many claimed by other countries in the region.
The Pentagon was alerted to the Chinese flight Friday. It was the first long-range flight of a Chinese bomber along the U-shaped line of demarcation since March 2015, according to the officials. Over the summer, Chinese bombers flew over the South China Sea and the contested islands, but they did not fly nearly as far as this one, the officials said.
At various points in recent long-range flights, Chinese fighter jets provided escorts to the single Chinese bomber.
In recent days, U.S. intelligence satellites have spotted components for the Chinese version of the SA-21 surface-to-air missile system at the port of Jieyang, in southeast China, where officials say China has made similar military shipments in the past to its islands in the South China Sea.
Just as concerning for the Pentagon, China has been seen by American intelligence satellites preparing to ship more advanced surface-to-air missiles to its contested islands in the South China Sea.
