WTO Director-General Pascal Lamy, in launching the World Trade Report 2011 on 20 July 2011, warned that preferential trade agreements (PTAs) “may lock in their members to a particular regulatory regime reducing the potential for trade to prosper with countries outside the arrangement”.
“The new challenge posed by deep PTAs to the multilateral trading system is one of market segmentation because regulatory systems, which can become divergent, have now more importance on trade flows than tariffs,” he added.
