China, in an early test of U.S. President Donald Trump, is nearly finished building almost two dozen structures on artificial islands in the South China Sea that appear designed to house long-range surface-to-air missiles, two U.S. officials told Reuters.
The development is likely to raise questions about whether and how the United States will respond, given its vows to take a tough line on China in the South China Sea.
China claims almost all the South China Sea, which carries a third of the world's maritime traffic. Brunei, Malaysia, the Philippines, Taiwan and Vietnam also have claims. Trump's administration has called China's island building in the South China Sea illegal.
