US National Security Adviser Tom Donilon Tuesday set the stage for a scheduled meeting next month between President Barack Obama and China's Xi Jinping as he pushed for deeper military ties between Beijing and Washington. On the final day of his visit to Beijing, Donilon met with General Fan Changlong, a vice chairman of the commission overseeing China's armed forces. "An essential part of building a new model for relations between great powers is ensuring we have a healthy, stable and reliable military to military relationship," Donilon told Fan at the Chinese Defence Ministry. "A healthy, stable, and reliable military-to-military relationship", he said, is an essential part of overall China-US ties. He stressed that the two countries should work closely on nontraditional military activities in areas like peacekeeping, fighting piracy and disaster relief.
