The trip follows the  landmark United States trip by Vietnam's Communist Party chief

"We have been transformed from former enemies to become friends, partners, comprehensive partners"

In sultry Hanoi, a joint Vision Statement to guide future military cooperation between the two former foes was inked

   "We need to modernize our partnership. After 20 years, there is more we could do together."

  China's relations with the United States remain stable, Chinese President Xi Jinping said on Sunday

But Hanoi remains more cautious than Manila in cheerleading

For many here, capitalism appears to be no longer anathema to Vietnam and its development

But no one in ASEAN besides Vietnam and the Philippines wants to confront China on its maritime claims. 

Vietnamese readers cheer after America's President asks China to behave.
