South Sudan President Seeks Help From China The president of South Sudan is in China seeking support for an oil pipeline meant to lessen his country's dependence on Sudan as a bomb attack by the northern neighbor threatened to trigger an all-out war. The trip marks President Salva Kiir's first visit to China since taking office. He opens a new embassy and meets President Hu Jintao on Tuesday. Sudan and South Sudan have been drawing closer to war in recent months over the sharing of oil revenues and a disputed border. Talks mediated by the African Union broke down in Ethiopia earlier this month. Tensions escalated Monday when Sudanese airstrikes killed at least two people near a major town in South Sudan.
