That is incorrect. OPE MADE BEFORE 12/31/2023 is allowed. And it is a stepped process done in phases over time, like 4 years (?) and different categories. Plenty of OPE is available like generators, trimmers, saws, etc.
Words have meaning, you probably meant to say NEW GAS OPE, not gas OPE as stated. Even that is not correct. And used OPE is not affected.
So many laws, so many lawyers, the deep state is very deep not just in the PRC.
