This treaty was necessary, because neither the Republic of China nor the People's Republic of China was invited to sign the Treaty of San Francisco due to disagreements by other countries as to which government was the legitimate government of China during and after the Chinese Civil War.
Denne traktat var nødvendig, fordi hverken Republikken Kina eller Folkerepublikken Kina blev opfordret til at undertegne San Francisco-traktaten på grund af uenigheder fra andre lande om, hvilken regering der var den legitime regering for Kina under og efter den kinesiske borgerkrig.
