Hello. I need your advice.

I will simply be passing through Shanghai Pudong on my way to Malaysia (originating from the USA). My flight arrives in terminal 2 via American Airlines and leaves from terminal 1 via China Eastern Airlines. I have roughly five hours between flights.

Can someone please tell me what procedure I will need to take in order to make this international transfer run smoothly? Will I need to claim my bags and then recheck them? I've read there is an international transfer hall in terminal 2 which leads me to believe that my bags will automatically be transferred between airlines. Is this true?

Please walk me through my scenario. Thank you, kindly.
