both better off

China will give up less software time or resources to produce hardware compared to U.S. while U.S. will give up less hardware time and resources to produce software. Both countries will benefit if they engage in trade, china should focus on the production of hardware while the U.S. should focus on the production of software. Trade in these product will benefit bith nations.
