Beijing: China on Monday accused the US of flexing its military muscles in the South China Sea by conducting joint exercises with two American aircraft carrier groups in the strategic waterway.
Foreign ministry's spokesperson Zhao Lijian said the exercises were performed "totally out of ulterior motives" and undermined stability in the area.

"Against such a backdrop, the US deliberately dispatched massive forces to conduct large-scale military exercises in the relevant waters of the South China Sea to flex its military muscle," Zhao said at a daily briefing.
The American Navy said over the weekend that the USS Nimitz and the USS Ronald Reagan along with their accompanying vessels and aircraft conducted exercises "designed to maximiseair defence capabilities, and extend the reach of long-range precision maritime strikes from carrier-based aircraft in a rapidly evolving area of operations."
