Final answer:
The latest shots in a trade war were between the United States and China.
Step-by-step explanation:
The latest shots in a trade war were between the United States and China. Tariffs on certain imported goods went into effect, sparking a series of retaliatory tariffs between the two countries. For example, in 2018, President Trump increased tariffs on Chinese-manufactured goods, which led to China imposing tariffs on American goods, thus initiating a trade war. The trade war has continued, with both countries implementing and adjusting tariffs on various products.
