Depending on your skills, (other than speaking Arabic) you can get a job in a tech support company (that caters to your home country), get a job doing localization on computer games & websites that will be seen in your country, or perhaps writing documentation for products to be sold in your company.

Granted, these jobs aren't very high paying, but they can make good use of your language skill.

I can honestly say that I only know of one person from an Arabic-speaking country that has landed a job in Beijing and that was at Beijiing Da as a junior lecturer in Arabic and Arabic studies. You may wish to look there but you will need the background and diplomas to go with it.

There should be all types of jobs for a native Arabic speaker. A translator would be one and also you can teach the arabic language in a class. They pay top dollars for knowing that language in the military so I would assume they would need your service. You could do anything educational such as teaching/tutoring or you can become a translator with a company that does business with Arabs. 

if you have a good English language  , you can work as English teacher ...this is very possible ..but you can  not do that in the main cities like shanghai or Beijing ..
