Answer:
Anxiety about imperialism is understandable. But China has a complicated relationship with imperialism. For much of its history, China was an empire itself. In the nineteenth century, however, it struggled against foreign imperialism. Decades of unequal treaties with Western nations and rising Japanese power meant that China had lost control of key ports, cities, and spheres of influence.
This situation was a large part of the reason why, in 1911, rebels started the Xinhai Revolution, overthrowing China's last imperial dynasty.
