US' national security strategy is still a work in progress

While highlighting the areas of cooperation with China, US President Donald Trump also identified it as a strategic competitor when he unveiled his national security strategy on Monday.

This is not the first time Washington has defined its ties with Beijing in this way.

Former president George W. Bush also described China as a strategic competitor when he first came to office. Yet over time, Bush came to see China as a "responsible stakeholder", paving the way for years of stability in Sino-US relations.
