Where can I find international tourism statistics?

I've searched the net high and low for international tourism statistics but cant really find the comprehensive list I was looking for (which might not even exist). I really need to know the number of tourists to most eastern European and southeast Asian countries (the ones that are/were communist). All I can find are a few figures from some countries' tourism bureaus. If anyone knows where I can obtain such statistics I'd appriciate it if you could point me in that direction.
Thanks.

 

CIA World Factbook?

Economics resources?

 

Local embassies (sp?)?

People are talking about natural disasters signalling the end of the world.

But, Bruce has actually given a straight answer to a question?






It's all over, folks!

 

Thanks guys.
I also found this site- www.wttc.org which ranks the size of travel and tourism economies, the economic activity generated by them, and much much more. It really provided the type of statistics I needed to write what I thought was a good proposal for a fellowship I am applying for. I hope the committee feels the same way about it as me...
