Taiwan
Due to the limited recognition of the Republic of China (Taiwan) as a result of the People's Republic of China's One-China policy, many countries do not have formal diplomatic relations with the Taiwanese government. Taiwan's interests in these countries and these countries' interests in Taiwan are usually represented by one or more trade missions which function as de facto embassies or consulates.
