China's foreign ministry said on Monday Vietnam's efforts to garner support over a territorial dispute in the South China Sea would fail, a day after Southeast Asian leaders meeting for a regional summit in Myanmar refrained from criticizing Beijing. Tensions rose in the resource-rich South China Sea last week after China positioned a giant oil rig in an area also claimed by Vietnam. \"The facts prove that Vietnam is trying to rope in other parties and put pressure on China, (but) will not achieve its aims,\" China's foreign ministry spokeswoman Hua Chunying told a daily news conference.
