Almost all of the lumber purchased in America is grown in China, and Chinese concrete and steel are increasingly more common, despite political half-measures intended to change that.
This is hilariously completely the opposite of true. China is a net importer of American lumber, almost no Chinese lumber is exported, especially to the USA.
Almost no concrete is ever shipped more than 150 miles or so, concrete is almost always extremely locally produced.
Only steel has any appreciable trade volume with China.
