I will be arriving in Beijing from Guangzhou on a China Southern flight.

And then transferring to a Delta flight to fly to America. I have about a 90-100 minute connection time. Here it says both China Southern and Delta use Terminal 2, is this still correct? Will my CZ flight from Guangzhou arrive in T2? If it does what will my connection time be enough for my international transfer within T2, I noticed that the transfer times in T3 were fairly long.
