Final answer:
During the age of imperialism, China experienced significant foreign influence, including the Opium Wars and the Open Door Policy. China responded to foreign influence through attempted reforms and the implementation of the Open Door Policy.
Step-by-step explanation:
During the age of imperialism, China experienced significant foreign influence from European and Asian powers. The Opium Wars, fought between China and Britain, were a major example of foreign influence. Britain forced China to accept the import of Indian opium, which greatly harmed the Chinese economy and society. This led to the signing of unequal treaties that allowed foreign powers to establish spheres of influence in China, further weakening the Qing Dynasty.
China responded to foreign influence in various ways. The attempted reforms by Emperor Guangxu, known as the Hundred Days Reform, aimed to modernize and westernize China. However, many Chinese opposed these reforms due to fears of the downfall of China. The Empress Dowager Cixi regained power and put an end to the reforms.
The Open Door Policy was introduced by the United States in 1899 to ensure equal trading rights for all nations in China. It aimed to prevent one country from dominating China's market. While it did not entirely stop foreign influence, the policy helped maintain some control for China.
