China's East-West Span: How Wide Is the Country?

The People's Republic of China stretches approximately 3,000 miles (4,800 kilometers) from its easternmost point (near the Ussuri River/Heilongjiang) to its westernmost point (in the Pamir Mountains/Xinjiang).

This vast width spans 5 geographic time zones, though the entire country officially uses a single time zone: China Standard Time (UTC+8).
