Answer:
D. China and the United States have very different forms of government, yet each country relies on the other for trade and commerce.
Step-by-step explanation:
China is governed by an authoritarian state, unlike the United States which is ruled by a democratic government. While in China is only permitted one political party, in the United States does not exist any restriction for political participation.
In spite of these differences, both countries are open and globalized economies where trade is necessary for both, China and United States.
