The document discusses China's increasingly assertive "frown diplomacy" in Southeast Asia regarding territorial disputes in the South China Sea, in contrast to its previous "smile diplomacy." It describes how China strongly urged ASEAN countries not to discuss the South China Sea at a July 2010 meeting, but several countries did anyway, angering China. It also summarizes comments by Hillary Clinton on the US position regarding maritime disputes and international law. Going forward, China, ASEAN countries, and the US all need to find a cooperative approach to resolve disputes peacefully according to international law.
