This policy created by John Hay was known as the Open Door Policy.
The goal of this policy would be to allow European countries and America to trade with China on an equal basis. John Hay wanted to ensure that no one country had a monopoly on the trade with China during the early 20th century. Along with this, he felt that the Open Door policy would result in less fights/confrontation between the countries involved in this trade.
The election of Andrew Jackson dramatically changed the US for several different reasons including:
1) He was an advocate for the "average citizen"- Andrew Jackson was dubbed the "Champion of the Common Man." He received this title because he was not an inherently wealthy man nor was he part of a family that was consistently in politics. Rather, he came from humble beginnings. This story inspired many American citizens.
2) His policies resulted in increased democracy in the US- Jackson helped to get rid of property qualifications and other restrictions to ensure that white farmers had the right to vote, regardless of how much property they owned.
