UPDATE 1-China, US defence chiefs hold talks at Asia security summit

Chinese Defence Minister Wei Fenghe and acting U.S. Defence Secretary Patrick Shanahan held talks on Friday at an Asia security summit in Singapore, amid heightened tensions between the two countries over trade and security.

The United States and China, locked in an escalating trade war, are also at odds over a series of strategic issues, from the disputed South China Sea to democratic Taiwan, claimed by China as its sacred territory, to be taken by force if needed. Shanahan - who on his first day in his role in January said the U.S. military would focus on "China, China, China" - told reporters ahead of his meeting with Wei that China's military actions in the disputed South China Sea had been "excessive".

"They argue that it is defensive, it looks like it's a bit overkill, surface to air missiles, long runways, it seems excessive," Shanahan said. China and the United States have repeatedly traded barbs over what Washington says is Beijing's militarisation of the South China Sea by building military installations on artificial islands and reefs.

China claims almost all of the strategic waterway and blames the United States and its allies for escalating tensions by carrying out naval operations in the region.
