The relationship between imports and exports in a mercantilist economic system is that one superpower dominates the imports and exports of another country. To further explain this, here is an example: when the British still held control over the American colonies they only let the colonies import from Great Britain and export to Great Britain, so that Britain was the only country to gain from this while the other European superpowers and the colonies were halted from making economic gains.
I know it's short but hey it's something.
Ummm sure what u need help with
The Townshend Acts were a series of measures, passed by the British Parliament in 1767, that taxed goods imported to the American colonies. But American colonists, who had no representation in Parliament, saw it as an abuse of power. The British sent troops to America to enforce the unpopular new laws, further heightening tensions between Great Britain and the American colonies in the run-up to the American Revolutionary War.
The USA wanted to prevent areas of the world falling under Communist influence. The Cold War was at its height in the late 1940s and early 1950s, when the French appealed to the USA for aid. The US government saw Vietnam as another Korea.
