This cartoon confirms once more the unfortunate but expected American misunderstanding of the issue of Vietnamese boat people. Starting in 1979, under a policy imposed by Britain, Hong Kong was made a nation of "first asylum" to accommodate tens of thousands of Vietnamese refugees whose intended final destination is the United States or another Western country. These countries, however, have never seemed eager to grant refugee status to most of the Vietnamese.Hong Kong has been one of few places to shoulder this burden, with little help from developed countries, yet it still has endured much unjustified criticism.
