Sino-US tension eases in runup to talks

Experts say maritime issue won't lead to conflict because nations will protect shared interests

Following months of diplomatic clashes over the South China Sea, Sino-US relations seem to be headed for calmer waters after key events in the lead-up to a major meeting between the two countries.

The maritime tension may have been eased by a top Chinese military official's visit to the US this month, and by the fact that US President Barack Obama suffered a setback to his hopes of pushing through the Trans-Pacific Partnership - a development that might result in a renewed focus in Washington on its ties with China. The TPP is a proposed regional investment and regulatory treaty.
