Because buying on one exchange and selling on the other is not a simple or immediate process. Different market participants. Different brokers offering different access to different exchanges. Different liquidity. Probably also various tactics being used due to the staggered trading hours of the two exchanges to throw investors the wrong way. Over time the price should be pretty much in sync, but you will get discrepancies short term. They should iron out a bit more once US has been trading a few more days. Likely plenty of other reasons too.
