managing international relations, although it was short on personnel. On 9 January 1943, the Reorganized National Government signed the "Treaty on Returning Leased Territories and Repealing Extraterritoriality Rights" with Japan, which abolished all foreign concessions within occupied China. Reportedly the date was originally to have been later that month, but was moved to January 9 to be before the United States concluded a similar treaty with Chiang Kai-shek's government. The Nanjing Government then took control of all of the international concessions in Shanghai and its other territories. Later that year Wang Jingwei attended the Greater East Asia Conference as the Chinese representative. The Wang Jingwei government sent Chinese athletes, including the national football team, to compete in the 1940 East Asian Games, which were held in Tokyo for the 2,600th anniversary of the legendary founding of the Japanese Empire by Emperor Jimmu, and were a replacement for the cancelled 1940 Summer Olympics. State ideology After Japan's pivot towards joining the Axis powers (which included signing the Tripartite Pact), Wang Jingwei's government promoted the idea of pan-Asianism directed against the West, aimed at establishing a "New Order in East Asia" together with Japan, Manchukuo, and other Asian nations that would expel Western colonial powers from Asia, particularly the "Anglo-Saxons" (the U.S. and Britain) that dominated large parts of Asia. Wang Jingwei used pan-Asianism, basing his views on Sun Yat-sen's advocacy for Asian people to unite against the West in the early 20th century, partly to justify his efforts at working together with Japan. He claimed it was natural for Japan and China to have good relations and cooperation because of their close affinity, describing their conflicts as a temporary aberration in both nation's history. Furthermore, the government believed in the unity of all Asian nations with Japan as their leader as the only way to achieve their goals of removing Western colonial powers from Asia. There was no official description of which Asian peoples were considered to be included in this, but Wang, members of the Propaganda Ministry, and other officials of his regime writing for collaborationist media had different interpretations, at times listing Japan, China, Manchukuo, Thailand, the Philippines, Burma, Nepal, India, Afghanistan, Iran, Iraq, Syria, and Arabia as potential members of an "East Asian League." From 1940 onwards, the Wang Jingwei government depicted World War II as a struggle by Asians against the West, more specifically the Anglo-American powers.
