BEIJING -- Retail sales of China's new energy vehicles (NEVs) continued to soar in December 2022, the China Passenger Car Association said on Tuesday.

Retail sales of China's new energy passenger cars came in at about 640,000 units, up 35.1 percent year-on-year.

The monthly figure is 6.5 percent higher than the previous month, according to the association.

From January to December, some 5.67 million new energy passenger cars were sold via retail channels in the country, skyrocketing 90 percent from a year ago.

The combination of improved supply and high oil prices has led to a NEV market boom, the association said.
