Q. The signing of the Nine Powers Treaty recognized the sovereignty of which of the following countries?
Answer: China
Notes: The Nine-Power Treaty, signed in 1922, recognized the sovereignty of China. The treaty was signed by all attendees of the Washington Naval Conference, including Belgium, China, France, Great Britain, Italy, Japan, The Netherlands, Portugal and United States. The treaty affirmed China's sovereignty, independence, and territorial integrity. It also gave all nations the right to do business with China on equal terms. The treaty upheld the Open Door policy that America had followed for years, but expanded it to the rest of the world powers. The treaty was meant to reassure China that its territory would not be further compromised by Japanese expansion. Japan had taken control of the area from the Germans during World War I and maintained control of it over the years that followed.
