The WTO had a long-drawn-out disagreement over the USA restricting imports of shrimps caught by countries like Mexico with nets that endanger wildlife (The Times, 28 April 1998). One problem is that signatory countries have less control over their imports because quotas and restrictions can be interpreted as trade barriers, which are outlawed (Bown, 1990; Westlund, 1994). There are also worries that free trade could favour developed countries’ biotechnology (Acharya, 1991).
