Vice President Xi Jinping — China's presumed next leader — emphasized economic ties and civic exchanges in remarks to delegates from the 10 countries that make up the Association of Southeast Asian Nations. Xi avoided mentioning South China Sea territorial disputes with the Philippines, Vietnam and others that have flared up again this year. “We are always committed to common development and steadily improving cooperation mechanisms in various fields," Xi said in his address at the annual meeting, held in the southern Chinese city of Nanning. With two-way trade growing 20 percent annually to $362.8 billion last year, China and its southern neighbors are increasingly intertwined, requiring even greater cooperation across a range of fields, Xi said. The contrasting approaches highlight Beijing's desire to keep the South China Sea disputes in check and avoid drawing in China's chief rival, the United States, which maintains close ties with many countries in the region. While eager to assert its claims, Beijing needs a peaceful regional environment to achieve its development goals and has a limited capacity to handle multiple diplomatic crises simultaneously. Fury at Japan followed the Japanese government's purchase last week of islands in the East China Sea from their private owners. The tiny, uninhabited archipelago, which is controlled by Japan but claimed by China, has been a lightning rod for simmering Chinese hatred toward Tokyo deriving from Japan's brutal invasion and occupation of parts of China in the first half of the 20th century. On Wednesday, Xi told US Defense Secretary Leon Panetta that Japan must “rein in its behavior," while Defense Minister Liang Guanglie said China reserved the right to take unspecified “further actions" over the issue. Chinese protesters gathered for days outside Japan's embassy and consulates, while mobs burned and smashed Japanese cars, factories, and businesses. The fury has also been directed at the US, which includes the islands — called Senkaku by Japan and Diaoyu by China — under its Treaty of Mutual Cooperation and Security with Japan despite claiming to take no sides in the sovereignty dispute. — AP
