New laws in China will enable thousands of automotive aftermarket companies to sell products there legally, according to the Diamond Bar-based Specialty Equipment Market Association.

Founded in 1963, SEMA is a trade association representing the $38 billion-a-year automotive specialty-equipment industry.

"Legal uncertainties have been a major deterrent to our members' participation in the growing Chinese automotive market," said SEMA Chairman Jim Cozzie. "This pro-industry amendment sends an important signal to Chinese consumers and SEMA members that car personalization is legal and welcomed by the government of China."
