NEW DELHI (Reuters) - United States Secretary of State John Kerry on Wednesday (Aug 31) called on China and the Philippines to abide by an international tribunal's decision on the disputed South China Sea region.

"This is a crucial opportunity to uphold the existing rules-based international order, show respect for international law, and support regional stability and prosperity," Mr Kerry said in an address to students on a two-day visit to New Delhi.

The remarks came ahead of a Group of 20 summit in China on Sept 4 and Sept 5 that is to be attended by global leaders.

Beijing wants to use the meeting in the tourist hub of Hangzhou to lay out a broad strategy for global growth, but talks are likely to be overshadowed by arguments over everything from territorial disputes to protectionism, diplomats said.
