Which country's military spending substantially surpasses China's in 2010?

In 2010, the United States had military spending that significantly exceeded that of China. This can be attributed to various factors including a global military presence, a large number of overseas bases, and expansive defense budgets that support advanced technology and capabilities. Compared to China's military expenditure during that time, which was increasing but still at a lower level, the U.S. investment in defense was driven by a commitment to maintain a dominant military status and to engage in numerous international operations. This level of spending illustrated the differences in military strategy and global influence between the two nations, reinforcing the U.S. as a leader in defense capabilities.
