According to Pascal Lamy, Director-General of the WTO, the proliferation of RTA “...is breeding concern — concern about incoherence, confusion, exponential increase of costs for business, unpredictability and even unfairness in trade relations.”
Prema Paskal Lemiju, generalnom direktoru STO, produktivnost regionalnih sporazuma "...je uznemiravajuća briga - brige nekoherentnosti(nepovezanosti), nedoumica, eksponencijalnog rasta cena u poslu, nepredvidivost i čak nepravednost u trgovinskim odnosima."
