Article 11 of the Patent Law stipulates that after the patent right for invention and utility model is granted, no unit or individual may exploit the patent without the permission of the patentee, that is, it shall not manufacture, use, promise to sell, sell or import the patented product for the purpose of production and operation, and shall not use the patented method and use, promise to sell, sell or import the product directly obtained according to the patented method.
As the utility model patent is authorized in China, its patent protection is limited to manufacturing, using, promising to sell, selling and importing in China, which is related to whether it is legal to manufacture in China. If it is legal, exhaustion will not infringe. If it is illegal, the utility model you made will be infringed.
