SINGAPORE, June 1 (Reuters) - Tensions between the United States and China are expected to loom over Asia's top security meeting this week, as China has declined a bilateral meeting between the superpowers' defence chiefs. The Shangri-La Dialogue, which attracts top defence officials, senior military officers, diplomats, weapons makers and security analysts from around the globe, will take place June 2-4 in Singapore. More than 600 delegates from 49 countries will attend the meeting, which opens with a keynote address by Australian Prime Minister Anthony Albanese. China's new Defence Minister Li Shangfu, however, has declined to meet U.S. Defence Secretary Lloyd Austin, the Pentagon said on Monday. Other key issues that are likely to be discussed include ongoing tensions in the disputed South China Sea and East China Seas.
