The prospect of an actual shooting war between China and Japan got a little realer this week as both sides raised the stakes in the showdown over the barren East China Sea chain known as the Diaoyu Islands to the Chinese and as the Senkaku Islands to the Japanese. Over the weekend, angry anti-Japan protests spread to 85 cities across China. In Beijing, protesters besieged the Japanese embassy, hurling rocks, eggs and bottles. Police fired tear gas and used water cannon on thousands of protesters occupying a street in Shenzhen, Guangdong province. Protesters broke into a Panasonic plant and several other Japanese-run factories as well as a Toyota dealership in Qingdao, Shandong province, ransacking and torching. In Shanghai, hundreds of military police were brought in to break up protesters outside the Japanese consulate, who chanted: ''Down with Japan devils, boycott Japanese goods, give back Diaoyu!''

The campesino communities of Ayavaca and Huancabamba in Peru's northern Piura region held assemblies Aug. 16 and issued a statement pledging to resist recently announced plans by Chinese mining company Zijin to move ahead with the long-contested Río Blanco copper project. The communities cited the need to protect threatened watersheds, wetlands and cloud forests in the high Andean region, noting that they have been officially listed as "fragile ecosystems" under Peruvian law. The local jalca ecosystem, which exists only in Peru's northern Andean regions near the border with Ecuador, is richer in water than the more arid high plains known as punas elsewhere in the country. Read the statement: "Ayavaca and Huancabamba are today more alert than ever and ready to commit our lives for the defense of water for future generations." (Megaproyectos, Aug. 16; CONDESAN)

On Aug. 15—not coincidentally, the 67th anniversary of Japan's surrender in World War II—a group of Chinese activists who had sailed from Hong Kong landed on Uotsurijima, one of the contested Senkaku Islands, and were promptly arrested by Japanese Coast Guard troops and Okinawa prefectural police. They succeeded in planting a Chinese flag on the island before five were arrested; another two managed to return to their fishing vessel and escaped. Japanese authorities say they will determine whether the detained men, now being held in Okinawa, will be prosecuted or deported back to Hong Kong. This was the first such incident since March 2004. But since 2009, the Hong Kong government has on six occasions stopped protest vessels from going to the contested islands. (Daily Yomiuri, Aug. 16; Xinhua, Japan Times, Asahi Shimbun, Aug. 16

China's move to set up a military garrison at Sansha on disputed Yongxing Island (also known as Woody Island) in the Xisha chain (claimed by the Philippines as the Paracels), along with creating a city administration for the island which has heretofore had few permanent inhabitants, is escalating tensions in the South China Sea (or, as Manila has it, the West Philippine Sea)—the key theater in Washington's new cold war with Beijing. On Aug. 4, Beijing summoned a senior US diplomat, the embassy's deputy chief of mission Robert Wang, over State Department criticism of the move. State Department spokesman Patrick Ventrell said in a statement the day before that the US is "concerned by the increase in tensions in the West Philippine Sea and [we] are monitoring the situation closely."

Regional security has been seen as the biggest challenge for the planned trans-Afghan gas pipeline—officially the Turkmenistan-Afghanistan-Pakistan-India (TAPI) project, which would pass the war-torn Afghan provinces of Herat and Kandahar as well as Pakistan's restive Baluchistan province. But recent reports of a rival pipeline project being negotiated between China, Turkmenistan and Afghanistan may pose a more fundamental threat to the TAPI. On June 6-8, on the sidelines of the Shanghai Cooperations Organization summit in Beijing, Afghan President Hamid Karzai met with Chinese President Hu Jintao and China National Petroleum Corporation's (CNPC) head Jiang Jiemin to discuss the proposal. CNPC offered to conduct a technical and economic feasibility study for the proposed project on Afghan and Tajik territories. That the route would avoid the conflicted Pashtun-dominated areas of southern Afghanistan, making the project more attractive for investors. India's Institute for Defence Studies and Analyses says the Chinese pipeline could undermine the TAPI "akin to the manner in which TAPI played spoiler to the Iran-Pakistan-India (IPI) pipeline project."
