The share of duty free tariff lines in South-south agreements is expected to increase from 28% to approximately 92% when frilly implemented, while North-South agreements increase their share of duty free lines from over 68% to only 87% (Fulponi et al, 2011). For example, cereal markets across South Asia (especially Bangladesh-India rice and Pakistan-Afghanistan wheat) are increasingly connected. As a result, cereal price policies have major spill-over effects across borders.
