Flying on China Southern from SIN to OVB (that's in Russia) via CAN and URC this coming November. I have a 3 hr 30 mn layover in Guangzhou and a 1 hr 40 mn layover in URC. I've never been to China and speak not a word. My Russian is very strong though and English is my native tongue. I anticipate having no visa, checking no bags, will never leave an airport or even exit immigration (I hope) on my way. Still though, I am antsy and am thinking about a SIN to CDG or AMS option and then going to SVO and OVB on my second airline of choice SU.

So, help me with the following please:

1. Can I make the necessary transfers at CAN and URC with no visa?
2. If I need a visa what is the process (including cost) for a transit visa...if such a thing exists in China?
3. Assuming weather is fine and delays are nill, do the connection times seem enough given airport layout and such?
4. Any lounge access in CAN or URC for a Sky Team Elite Plus guy?

ANY help, suggestions, warnings will be duly noted and considered worthy of my attention.

Many thanks!
