China will set a deadline for automakers to end sales of fossil-fuel-powered vehicles, becoming the biggest market to do so in a move that will accelerate the push into the electric car market led by companies including BYD Co. and BAIC Motor Corp. The deadline date is still to be decided but current speculation is in the 2040-2050 timeframe.

Xin Guobin, the vice minister of industry and information technology, said the government is working with other regulators on a timetable to end production and sales. The move will have a profound impact on the environment and growth of China's auto industry, Xin said at an auto forum in Tianjin on Saturday.

The world's second-biggest economy, which has vowed to cap its carbon emissions by 2030 and curb worsening air pollution, is the latest to join countries such as the U.K. and France seeking to phase out vehicles using gasoline and diesel.

The U.K. said in July it will ban sales of diesel- and gasoline-fueled cars by 2040, two weeks after France announced a similar plan to reduce air pollution and meet targets to keep global warming below 2 degrees Celsius (3.6 degrees Fahrenheit). Norway and the Netherlands are considering a more aggressive way to put an end on fossil fuel cars years earlier than its European peers.
