The China–United States trade war refers to the ongoing economic conflict between China and the United States. It began in 2018 when President Donald Trump's administration imposed tariffs on Chinese goods in an effort to reduce the United States' trade deficit with China and to address what the administration saw as unfair Chinese trade practices. China responded by imposing tariffs on American goods.

The tariffs have affected a wide range of products, including automobiles, agricultural products, and technology. The trade war has led to increased costs for businesses and consumers in both countries, and has caused uncertainty in global markets. The two countries have engaged in several rounds of negotiations in an effort to resolve the trade war, but so far, a comprehensive agreement has not been reached.

The Trump administration has also taken several other actions to pressure China, such as limiting Chinese investment in the US and restricting the activities of Chinese technology companies like Huawei. The Trump administration has also placed tariffs on several other countries' goods, in addition to China.

The trade war has had a negative impact on the global economy, as it has led to a slowdown in trade and increased costs for businesses. It has also led to job losses in industries that rely on exports to China and the US. The trade war has also strained relations between the two countries, with China and the US accusing each other of unfair trade practices.

After the Trump Administration, the current president Joe Biden has announced that his administration wants to continue talks with China to resolve trade disputes, but has also stated that they will not back down on issues such as human rights, intellectual property theft and forced labor.
