1763 what policies did Britain implement to suppress the economy of the north American colonies?

1763, Britain strengthened the measures to punish the smuggling industry in North America, and sent a large number of warships to the coast of North America to investigate smuggling, which dealt a heavy blow to the foreign trade of North America and quickly plunged the economy of coastal port cities into depression.

In the same year, the British government issued a decree prohibiting colonists from migrating to the west of the Appalachian Mountains to protect the interests of British fur traders. This measure dealt a blow to all strata in the colony, because farmers expected to make a living in the west, while planters and bourgeoisie wanted to go there to develop plantation economy and speculate on land. When Washington was a surveyor in his early years, he knew the situation of the land in the west and its great potential value, and he was eager to develop his own business in the west. So this decree is also a big blow to him.

It seems that the British authorities are still insufficient. After 1764, they promulgated a series of new tax laws, such as 1764 sugar tax law, 1765 stamp tax law and 1767 townsend tax law. And impose taxes on the people of North America.
