Can I get the Z visa while in BKK on a tourist visa?

Hello, I was working in BKK, but now have accepted a job in China. So my Thai work permit has been cancelled and therefore my non-B visa also has been cancelled. Now I'm in BKK on a 30 day (on arrival) L type.

Does anyone know if the Chinese Embassy in BKK will process the Z type for me now that I'm on a L type and no longer on a non-B type?

I have a US passport. I plan to check with the embassy here, but it has been difficult reaching someone who could actually answer any questions. Any help would be appreciated.

Thanks!
