Saudi Arabia. Saudi Arabia ended its diplomatic relations with the ROC in 1990. Ambassador Wang Shi-ming was a Chinese Muslim, and the ROC ambassador to Kuwait. The ROC also maintained relations with Libya and Saudi Arabia. Africa South Africa switched in 1998. Liberia recognised the ROC in 1989, and switched back to the PRC in October 2003. In December 2016, the government of São Tomé and Príncipe switched. Burkina Faso has recognised the ROC since 1994, but cut diplomatic ties in May 2018, establishing relations with the PRC. Earlier, Burkina Faso had rejected US$50 billion from China to break ties with Taiwan. Eswatini After Burkina Faso cut relations with Taiwan in 2018, Eswatini became Taiwan's sole ally in Africa. Taiwan has an embassy in Mbabane, Eswatini. On 7 June 2016, the National Police Agency and Royal Eswatini Police Service signed a joint, cross-border, crime fighting pact, which included exchanges, probes, personnel visits, professional skills enhancement, law enforcement and technical assistance. King Mswati III has visited Taiwan seventeen times as of June 2018, and has promised to continue recognising Taiwan instead of the PRC. As of June 2018, the Taiwanese Ambassador is Thomas Chen (). The Gambia The Gambia recognised the ROC from 1968 until 1974, and then again from 1995 until 14 November 2013, when President Yahya Jammeh's office announced it had cut diplomatic ties with immediate effect. During this era Taiwan gave hundreds of millions of dollars in aid and loans to The Gambia, much of which was diverted by President Yahya Jammeh and those close to him. The PRC recognised The Gambia on 17 March 2016. Upon Gambian recognition the PRC immediately began to furnish them with aid. The repeated switch off between PRC and ROC recognition is seen as an example of checkbook diplomacy. Americas Dominican Republic On 1 May 2018, the Dominican Republic switched.

It was motivated by loans and investments worth US$3.1 billion. "History and socioeconomic reality" were cited as reasons for the switchover.
