Answer:
China is the world's leading exporter.
Step-by-step explanation:
American trade was limited to China because they are the world's leading exporter. The U.S. trade with China is part of a complex economic relationship. In 1979 the U.S. and China reestablished diplomatic relations and signed a bilateral trade agreement. This gave a start to a rapid growth of trade between the two nations: from $4 billion (exports and imports) that year to over $600 billion in 2017. Today, the United States imports more from China than from any other country, and China is one of the largest export markets for U.S. goods and services. This trade has helped the United States in the form of lower prices for consumers and higher profits for corporations, but it has also come with costs.
