This time zone is used in all Chinese-speaking countries, giving international Chinese websites and TV channels the same time.
The southern half of Vietnam (Republic of Vietnam) was formerly part of this time zone prior to the national reunification on 30 April 1975, making it 1 hour ahead of North Vietnam. After 1975, the whole country came under the North Vietnamese time zone, UTC+07:00.
