and the Fu-Go balloon bomb campaign. Canada The gold rush fever spread progressively north; in 1858, the Fraser Canyon Gold Rush began in British Columbia, and at the end of the century, the Klondike Gold Rush saw the Yukon hit by masses of prospectors. The formal delineation of the international border had not completely allayed Britain's fears of losing its Pacific territories, especially as it continued to lag behind the western United States in population and development. As a condition of British Columbia's joining Canadian Confederation in 1871, the Canadian government promised British Columbia a railway, though due to the Pacific Scandal and controversies over the location of the Pacific port and railhead and the use of importing Chinese labour, the Canadian Pacific Railway was not completed until 1885. The new line became an important link in what was known as the All Red Route around the world, linking global travel through territories of the British Empire. Mexico While the Pacific Coast of Mexico remained relatively undeveloped economically, exceptions were tobacco cultivation in the coastal territory of Nayarit, tourism at Acapulco, and local-scale fishing all along the coast. Central America The countries of Central America continued to struggle politically during this time (with perhaps the notable exception of Costa Rica), and began to expand agriculture, particularly in coffee and bananas with investment and substantial control by the United States. The establishment in 1903 of the newly independent nation of Panama (under pressure from the United States) led to the creation of the Canal Zone and opening of the Panama Canal in 1914. The opening of the Canal benefited the region economically as trade with the Eastern United States and Europe became far easier. Immigration Both the gold rushes and the building of the railroads required vast amounts of labor. One available source that was used on both sides of the border were immigrants from East Asia, largely from China and Japan. These immigrants were willing to work for very little and played a crucial role in building the infrastructure of the west coast. However, they faced constant discrimination. Asians were deprived of their civil rights in both the United States and Canada. There was also pressure to restrict Asian immigration, opinions that were acted on with quotas, head taxes, and finally a complete ban in both nations in the 1920s. Because of discrimination, and also a desire to remain a
