China Foreign Minister: "I Have Suggestion For My American Friends: Brush Up On The History Of World War Two"

While Trump has been busy focusing on the US judicial system in recent days, letting the simmering conflict with China over trade and the disputed South China Sea islands slide to the back burner, China has remained on the diplomatic offensive, and in overnight remarks cited by Reuters, China's Foreign Minister Wang Yi said the United States "needs to brush up on its history about the South China Sea, as World War Two-related agreements mandated that all Chinese territories taken by Japan had to be returned to China."

China remains upset by previous comments from the new U.S. administration about the disputed waterway. In his Senate confirmation hearing, Secretary of State Rex Tillerson said China should not be allowed access to islands it has built there. The White House also vowed to defend "international territories" in the strategic waterway.

Perhaps in an attempt to deescalate the situation, and offer an olive branch, last week U.S. Defense Secretary Jim Mattis suggested that diplomacy should be the priority in the South China Sea. However, that was insufficient for China, and in comments carried on the foreign ministry's website late on Tuesday, Wang said he had a "suggestion" for his American friends. "Brush up on the history of World War Two," Wang was quoted as saying during a visit to Canberra, Australia.

Wang added that the 1943 Cairo Declaration and 1945 Potsdam Declaration "clearly state that Japan had to return to China all Chinese territory taken by Japan. This includes the Nansha Islands," he added, using China's name for the Spratly Islands.

"In 1946, the then-Chinese government with help from the United States openly and in accordance with the law took back the Nansha Islands and reefs that Japan had occupied, and resumed exercising sovereignty," Wang said.

"Afterwards, certain countries around China used illegal methods to occupy some of the Nansha islands and reefs, and it's this that created the so-called South China Sea dispute."

China is committed to having talks with the parties directly involved, and in accordance with historical facts and international law to peacefully resolve the issue, and that position will not change, Wang said, but added that countries outside the region should support the efforts of China and others in the region to maintain the peace and stability of the South China Sea, and not do the opposite.

For now the ball is in Trump's court: Wang concluded by saying that China sets great store on Mattis' comments stressing diplomatic efforts in the South China Sea, as this is not only the position set by China and Southeast Asia but also the "correct choice" for countries outside the region.

Assuming Trump's immigration ban is escalated to the Supreme Court, he will likely have his hands full with domestic issues for a long time, which also means that any incipient diplomatic spat with China will most likely fizzle on its own.
