What two countries were causing trouble with American ships in the late 1700s and early 1800s?

Britain and France are the two countries were causing trouble with American ships in the late 1700s and early 1800s.

Explanation:

During the 17th century Britain forced men to join navy even without their concern. This men disliked and started to desert the ships and went to work in American ships. So Britain was very angry and they searched the ships of America and took the British citizen by force. In this some Americans also was taken by mistake.

The other problem was trade with France where the American ships were always checked and if any France goods were found in the ship the goods were seized and the owners were asked to pay a huge amount to release the ship. When the American ships went out in water it was either seized by the British or France government.
