Thailand
Thailand is one of America's biggest fans. According to a 2014 poll, 73% of Thai people have a favorable view of the U.S. compared to 15% unfavorable. However, because two-thirds of Thailand's population are rice farmers, U.S. farm subsidies for rice have constituted a number of major problems in the U.S.-Thai trade ties.
Wales
The U.S. has established a caucus to build direct relations with Wales called the Friends of Wales Caucus, which is made up of legislators with Welsh heritage and interests in Wales. A mere 0.6% of Americans have Welsh ancestry.
