What was a result of us actions in Mexico and china?

1. Mexican-American War (1846-1848): The U.S. victory in the Mexican-American War resulted in the acquisition of vast territories in the Southwest, including present-day California, Arizona, New Mexico, Nevada, Utah, and parts of Colorado and Wyoming. This expansion increased U.S. territorial control and set the stage for further westward expansion.

2. Chinese Exclusion Act (1882): In response to the influx of Chinese immigrants, the U.S. passed the Chinese Exclusion Act, which restricted Chinese immigration for ten years. It was later extended several times and effectively halted Chinese immigration to the U.S. for decades, leading to discrimination against Chinese Americans.

3. Boxer Rebellion (1899-1901): The U.S. joined other international forces in suppressing the Boxer Rebellion, a violent anti-foreign movement in China. The rebellion aimed to expel foreign influence and restore Chinese traditions. By participating in the suppression of the rebellion, the U.S. gained greater influence and presence in China.

4. Open Door Policy (1899-1900): Secretary of State John Hay proposed the Open Door Policy to ensure equal trade opportunities for all nations in China. The policy aimed to prevent any single nation from gaining exclusive control over Chinese markets and resources, thus maintaining an open and competitive environment for trade and investment.

5. Spanish-American War (1898): The U.S. victory in the Spanish-American War resulted in the acquisition of the Philippines, Puerto Rico, and Guam. This marked the beginning of the U.S. as an imperial power with overseas colonies. In the case of the Philippines, it led to the Philippine-American War (1899-1902), which resulted in the U.S. establishing control over the Philippines.

6. Spheres of Influence in China: During the late 19th century, various European powers and Japan carved out spheres of influence in China, where they held exclusive economic and political rights. The U.S., through the Open Door Policy, sought to maintain its access to these areas and prevent the complete domination of China by any single power.
