how can i apply for china visa from Thailand

Hi Nasser! Will you travel to China for leisure purpose? If yes, you can apply for the L type at the CVASC in Bangkok. The basic documents include your passport and a copy of its first page, a duly filled application form attached with your photo, and the original and photocopy of your entry permit to Thailand. The supportive application documents are your round-trip tickets and hotel bookings for the upcoming travel.
