President Xi Jinping and US President Donald Trump have agreed on a new vision of building a constructive bilateral relationship of strategic stability.

Observers said the move could help enhance China-US cooperation, manage differences between the world's two largest economies, and inject much-needed certainty into development for both countries and the world at large.

The vision, unveiled during Trump's three-day state visit to China last week, is expected to provide strategic guidance for bilateral ties over the next three years and beyond while sending a positive message to the world.
