25 October 1971, UN Resolution 2758 was adopted by 76 votes to 35 with 17 abstensions, recognizing the PRC, founded in 1949 on the mainland, as China's sole representative in the United Nations; countries in support included France, India, the UK, and the USSR, and countries in opposition included Japan and the United States. The PRC refuses to have diplomatic relations with any nation that has diplomatic relations with the ROC, and requires all nations with which it has diplomatic relations to make a statement recognizing its claims to Taiwan. As a result, only and the Holy See maintain official diplomatic relations with the Republic of China. The ROC maintains unofficial relations with most countries via de facto embassies and consulates called Taipei Economic and Cultural Representative Offices (TECRO), with branch offices called "Taipei Economic and Cultural Offices" (TECO). Both TECRO and TECO are "unofficial commercial entities" of the ROC in charge of maintaining diplomatic relations, providing consular services (i.e. visa applications), and serving the national interests of the ROC in other countries. From 1954 to 1979, the United States was a partner with Taiwan in a mutual defense treaty. The United States remains one of the main supporters of Taiwan and, through the Taiwan Relations Act passed in 1979, has continued selling arms and providing military training to the Armed Forces. This situation continues to be an issue for the People's Republic of China, which considers US involvement disruptive to the stability of the region. The official position of the United States is that the PRC is expected to "use no force or threat[en] to use force against Taiwan" and the ROC is to "exercise prudence in managing all aspects of Cross-Strait relations." Both are to refrain from performing actions or espousing statements "that would unilaterally alter Taiwan's status". Taiwan, since 2016 under the Tsai administration's New Southbound Policy, has pursued closer economic relations with South and Southeast Asian countries, increasing cooperation on investments and people-to-people exchanges despite the region's general lack of official diplomatic ties with Taipei. The policy has led to Taiwan receiving an increased number of migrants and students from the region. However, a few scandals of Southeast Asians, particularly Indonesians, experiencing exploitation in scholarship programs and in some labour industries have emerged as setbacks for the policy as well as for Indonesia-Taiwan relations.
