Chinese firms are encouraged by both Beijing and Washington to invest in the US infrastructure projects, according to WSJ. To avoid political rhetoric, Chinese firms will only take minority share and remain passive investors. And these projects should be mutual beneficial to the two countries: for China it’s a good way of diversifying its foreign exchange reserves; for the US, these infrastructure projects will bring jobs while not increasing government spending, which helps to improve government budget situation.
In general, this is a smart move on both sides.
