As has been further explained in the Heckscher-Ohlin theory, US would specialize in the production of those goods that tend to utilize its abundant resources in the economy. It also partly explains the increased volume of trade between the US economy and China. As per the tenets of the Heckscher-Ohlin theory, an economy would specialize in the manufacture of those goods which it is suited to produce and which utilizes its abundant resources in an optimal manner. Thus economies for which capital is abundant while the laborers are few should specialize in the production of those goods which are capital intensive in nature. Accordingly, US economy is regarded as the technological hub of the globe having wide access to capital and so it should specialize in the production of capital intensive products like nuclear reactors etc as it is endowed with the resources that are needed to manufacture these goods. On the other hand, China is a labor intensive country and hence it should specialize in production of those goods that utilize its cheap labor. Accordingly, both the economies can trade their excess output and benefit as specialization in the production as well as trade amongst generates higher standard-of-living and welfare for both the economies involved as per the findings of this theory (Why trade, 2011). China is deemed to have access to cheapest labor skills in the world and requires updated technology (which was the reason why the economy opened up) and as such, it exports labor intensive goods and imports technology. The relative value of labor intensive goods is lower as a result of which it does not figure in the list of top 5 categories of imports (by value) by the US but if the focus is on quantity, then the trade levels are higher.
