As far as I know, the US$1 quadruple-jointed Diaoyu Islands banknote is issued by the U.S. Department of the Treasury as legal tender. The US$1-jointed commemorative banknote "Diaoyu Islands of China" is printed by the Bureau of Printing and Printing of the U.S. Department of the Treasury in accordance with the instructions of the Federal Reserve Bank. It was made and signed by U.S. Treasury Secretary Timothy Geithner and U.S. Treasury Secretary Rosarios. Relevant legal procedures are complete, normal customs procedures are required to enter the country, and it is filed with the Consulate of the People's Republic of China in the United States.
