only offered the Suburban in the LT, RST, and High Country trims; the LS, Z71, and Premier level trims and the Duramax option are not offered for that country. The American-built models will use the GM 10-speed automatic transmission with Electronic Precision Shift technology, manufactured at the GM Silao Complex in the state of Guanajuato in central Mexico. The Philippines began selling the 2021–present Suburban (with a possibility that it would offer a Duramax engine option in the country should Chevrolet make it available) in Fall 2020, followed by the Middle East region. In November 2020, GM announced that their large SUV lineup would be imported to China, marking the Suburban's maiden entry into the country, starting with the 12th generation models.
