Need a Visa for US Citizen living in Nikolaev Ukraine

I am a US citizen and have been in Ukraine since last April. How should I make application for a Visa to China.
Previously I had a visa to China that was processed via a Houston Texas office in the US while I lived in Oklahoma. That was an "L" visa giving 60 days stay with multiple entries. This was back in September 22, 2009 - September 2010. I made to trips of about 2 to 3 weeks each time.
How should I go about getting a new and valid visa now? Via the Chinese Embassy in Kiev Ukraine?
Who should I contact specifically? What are my options, costs associated with each choice and turn-around time frame? Thank you for you help and if nothing more, please direct me to the person who can assist me best.
Have a wonderful day!
Sincerely
Steve Mandrino
