How did China become the main threat to OPEC?

According to a post on Yahoo, experts believe that the world's major oil suppliers, such as Saudi Arabia and OPEC, should not be worried about green energy deals in the West or cutting CO2 emissions to zero, but about China, which is the maximum threat. Sales of gasoline and diesel vehicles in China fell by 20%, while sales of electric vehicles rose to 32% of all standard passenger cars. China produces cheap electric vehicles for the mass market, which is not yet available in the West. If automakers can meet demand, China's electric vehicle penetration will reach 40% this year, and China's electric vehicle sales will reach 80% by 2030. Electric vehicles worldwide have already displaced 1.5 million barrels per day of oil use, Bloomberg New Energy Finance estimates. Experts believe that by 2030, half of China's car fleet could become electric, which will reduce the use of oil by several million barrels per day. In addition, the use of high-speed rail in China will reduce the demand for domestic airlines, which will also reduce the use of oil. OPEC+ still espouses the idea that oil demand will continue to rise until mid-century, but that assumption is outdated as the world's largest gasoline car market in China collapses.
