The Treaties of Tientsin uses several words that have somewhat ambiguous meanings. For example the words “settlement” and “concession” can often be confused. The term “settlement” refers to a parcel of land leased to a foreign power and is composed of both foreign and national peoples; locally elected foreigners govern them. The term “concession” refers to a long-term lease of land to a foreign power where the foreign nation has complete control of the land; it is governed by consular representation.
Following the pattern set by the great powers of Europe, the United States took on a protectionist stance, built up its navy, and tried to create a mercantile empire. The United States was one of the leading signing “treaty powers” in China, forcing open a total of 23 foreign concessions from the Chinese government. While it is often noted that the United States did not control any settlements in China, they shared British land grants and were actually invited to take land in Shanghai but refused because the land was thought to be disadvantageous.
