how and where to apply for chinese visa from morocco? thanks

Najib, you should apply from the embassy in Morocco. The address is 16, Charia Ahmed Balafrej - Souissi - Rabat.

First, you need to make an online appointment on the embassy's webite. Then go there on the arranged date and submit the required documents, including your passport, a photocopy of the passport's data page, a filled application form attached with your personal bare-headed photo agaisnt light background, and other supportive documents.
