International to International transfer in Terminal 2

I'm thinking of booking a flight from Chicago to Hong Kong. Hainan Airlines flies from Chicago to Beijing and then Hong Kong airline to Hong Kong. There is a 2 hour layover going and 2:55 returning. From what I can find, they both fly from T2, but I don't see any transfer information for T2. Is this enough time? Will I need to reclaim my baggage and recheck it in? What is the procedure for I-I transfers in T2?

Thanks!
