China and the United States wrapped up a three-day humanitarian relief military drill Friday, looking past simmering tensions over the disputed South China Sea and uncertainty at what Donald Trump's presidency will mean for defense ties.

The exercises, held in the southwestern Chinese city of Kunming, come a month after a U.S. Navy destroyer sailed near islands claimed by China in the South China Sea, prompting fury in Beijing, which called the moved illegal and provocative.

That patrol, the latest by Washington to challenge Chinese claims in the strategic waterway, capped a tense year for military-to-military ties between the world's two largest economies, which are also at odds over the U.S. decision to base Terminal High Altitude Area Defense (THAAD) anti-missile system battery system in South Korea to defend against North Korea.
