And some liberalization – say, of advanced economies’ cotton imports – would undoubtedly benefit some low-income economies. But full trade liberalization would have a complex impact on the least developed economies, some of which would benefit only if compensated for the loss of the preferential access to advanced-economy markets that they currently enjoy.
贸易谈判进展缓慢的主要原因并不是贸易保护主义的日渐增加；而是因为进一步自由化导致的复杂权衡取舍无法再被非常庞大的潜在利益所抵消。多哈回合的失败被认为是发展中国家所遭遇的挫折。同时一些自由化行动——比如发达国家的棉花进口——无疑会令一些低收入国家受益。但全面的贸易自由化会对那些最不发达的国家产生复杂的影响，其中一些国家可能会失去现在享有的通往发达经济体市场的优惠渠道，只有对此进行补偿才能让它们受益。
