How was the U.s. economic policy toward Japan and China similar during 19th century?

During the 19th century, the United States pursued a policy of "Open Door" towards Japan and China. This policy aimed to secure equal trading opportunities for all countries in these markets, preventing any single nation from gaining a dominant position.

To achieve this, the United States negotiated a series of treaties with both Japan and China, known as the "Open Door Notes". These treaties guaranteed that all nations would have access to the same tariffs and trade privileges, regardless of their political or economic power.

The Open Door policy was driven by a desire to expand American trade and influence in the Asia-Pacific region. By ensuring equal access to these markets, the United States hoped to increase its economic opportunities and prevent the emergence of a single dominant power that could challenge its interests.

However, the Open Door policy also reflected a broader commitment to the principles of free trade and equal opportunity. The United States believed that these principles were essential for promoting economic growth and stability, both at home and abroad. By championing the Open Door, the United States sought to create a more level playing field for international trade and to promote a more prosperous and peaceful world.
