Mr.Waseem, the procedures are complex if you want to travel through China by your own car.

first, For tourism, Pakistani citizens should first contact a qualified travel agency of China and settled down all the details of the tour. And then the tourist agency may arrange a visa notice form for a travel group (more than 5 people) and a group-visa for you. At present, individual tourists are not accepted.

second, Those who like to travel through China by his/her own vehicle or on foot have to find a travel agent in their own countries first. And then they should submit the document specifying the name list of the travelers, touring schedule (namely, port and time of entry, touring route, cities to call at and programs in China) and the vehicle information through the travel agent in their own countries to an authorized international travel agency in China three months in advance.
