What are the requirements for business travel? I am Lebanese work and live here in Jeddah K

The basic requirements are your original passport and its copy, completely-filled application forms (Form V2011A and V2011B), 2 recent passport photos , your Saudi resident card or its copy, and an introduction letter from your work unit in Saudi Arabia including the company license. The very important document you need is an invitation letter from China with a copy of their business license if the inviter is a company in China.
