I am a Cameroonian tourist in the Philipines. Can i apply for a Chinese tourist visa in Philipines?

Mark, I think it will be very difficult for you to apply in Philippines because you don't have the resident permit for employment and study. According to the embassy, you are required to apply in your country. If you are in need of it urgently, you may try to apply from Chinese embassy. However, the embassy has the final say. They decide whether you will be granted or not.
