Business Trip to China for 6 (six) months

1. It is impossible for you to get a business trip tp China from Saudi Arabia. Only long-term residents of third country nationals in Saudi Arabia can apply for China visa there. A photocopy of a valid residence permit in Saudi Arabia is required.

2. the required documents are:
(1) Original passport and a photocopy of its pages with personal information.

(2) fully completed Visa Application Form v.2011A with the applicant's signature and Form V.2011B

(3) An original letter from the applicant's employer. It should contain the applicant's name, nationality, occupation, purpose of the visit, the planned date of entry and financial conditions.

(4) An invitation letter from the Chinese side (original or a photocopy/fax).

(5)A passport photo with white background.

(6)A photocopy of a valid residence permit in Saudi Arabia (only for long-term residents of third country nationals).

(7)If other additional documents are required, consular officers will contact the applicant directly according to the contact information left on the Visa Application Form by the applicant.

You can't provide the item 3 and item 6.

Thanks for your quick response and explanation. But I have still a question as follow mentions:
1. What shall I do in the best way?
2. Whether I should back to Indonesia and to be processed from Indonesia?
3. How long can I be get for this visa? Whose agent can help me?
Thanks you for your attention.

Best regards,
Ivan

You need to go back to Indonesia to apply for Chinese business visa. It takes 4 working days if all required documents are provided and the procedure goes smoothly.
