Afro-Panamanian
In 1904 when the construction of the Panama Canal was taken over by the United States for the failure of the French company, will again resort to the West Indian worker. Although between 1904 and 1914 the vast majority of Afro-West Indians who arrived in Panama did a one-year contract with the idea of returning to their home islands once the offshore project, after construction of the canal many Afro-Antillean stayed in Panama. Afro-West Indians who remained in Panama many got jobs in the Canal Zone and became the largest immigrant group in Panama. On the subject of Afro-Antillean Panama, Leslie B. Rout said that when the canal was opened in 1914, some 20,000 African-West Indians remained in Panama.
Latin America–United Kingdom relations
London's interest in Central America began in the 17th century, focused first in Belize, Roatán, and the Mosquito Coast (which became the east coast of Nicaragua and Honduras). Washington's interest began in 1824 with the diplomatic recognition of the five states of Central America. Britain consolidated its hold on the Caribbean shore and an unforeseen result was a direct clash with the United States. In 1848 the U.S. saw the need a transoceanic canal, a plan reinforced by the flood of gold seekers using a Central-American transit route in 1849. One route under consideration went through Nicaragua but was frustrated by British control of the Mosquito Coast. This conflict was resolved in 1850 when the two powers agreed in the Clayton–Bulwer Treaty to renounce territorial possessions along the route of a possible canal. To prevent the domination of Pacific trade routes by the other, each agreed that any canal would be neutral and they would not acquire formal colonies on the route. In 1901 Britain renounced its claims in the Hay–Pauncefote Treaty, allowing the United States to build the Panama Canal, which opened in 1914.
