Can foreign patents be produced in China?

1. But it seems that there is no patent protection in China; There are two possibilities, 0 1. I really didn't apply for a patent in China.

02. Applied, but not made public;

If it is 0 1, there are two cases, 00 1. Not yet applied for and within the priority period; 002. Not applied for, and outside the priority period;

If it is 002, there is no problem in domestic production and sales, but it cannot be sold abroad; 00 1 02, you can produce and sell it, but when his application is made public in China, he has the right to inform you of the infringement, and after authorization, he has the right to ask you to pay royalties.
