can I apply for a visum at the Chinese embassy in Seoul, I am a dutch tourist

Dear ladies and gentlemen.

On May 18th I arrive in Seoul to visit my brother. He does an intership at the Kyungpook University in Daegu. The aim was (and still is) together to make a trip to China after his graduation. That trip was scheduled to stay in China from June 1 to August 18. Because his school, Avans in Breda, still not gives the date on which, via Skype, he can graduate I cannot get a visum for 90 days in the Netherlands, since we can not book tickets for the trip from Korea to China. That ticket, we can of course book in Korea, but the problem is: how do I get a visum? Question to you is: can I apply for a visum at the Chinese embassy in Seoul make a visa application? If necessary, perhaps a 60 days visa can be sufficient. I do have an ticket out of china to Amsterdam on 17 august 2011.

I wait your answer,

Loes Mevius.
