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.
History of Panama (1977–present)
Despite his continuing concern with the ambiguity of the treaties with respect to the United States role in defense of the canal after 2000, the close Senate vote made Torrijos aware that he could not secure any further modification at that time. On June 16, 1978, he and Carter signed the instruments of ratification of each treaty in a ceremony in Panama City. Nevertheless, Torrijos added the following statement to both Panamanian instruments: "The Republic of Panama will reject, in unity and with decisiveness and firmness, any attempt by any country to intervene in its internal or external affairs." The instruments of ratification became effective on June 1, 1979, and the treaties entered into force on October 1, 1979.
