What was the result of the U.S.-China treaty regarding some labor provisions before it was revoked?

The U.S.-China treaty regarding labor provisions aimed to encourage Chinese labor migration, which was significant during a period when there was a demand for labor in the United States, particularly in the West. This treaty facilitated the movement of Chinese workers, who played a crucial role in industries such as railroad construction and mining.

The incorporation of labor provisions in the treaty indicated a recognition of the contributions that Chinese laborers could make to the U.S. economy. By allowing and encouraging their migration, the treaty sought to address labor shortages in certain sectors, especially during times of economic expansion.

In contrast, other options such as enhanced military cooperation or increased economic sanctions do not directly relate to the primary focus of the labor provisions in the context of the treaty. Similarly, while restricted American exports could be a broader economic concern, it does not align with the specific aims of the treaty regarding labor mobility. Thus, the emphasis on encouraging Chinese labor migration serves as the most accurate interpretation of the treaty's intended outcomes.
