The analysis of the chapter points to a number of factors that contribute to the slow progress in the implementation of the initiatives to address NTBs. These include the difficulty in identifying the NTBs from among the NTMs, as some of the government regulations have evolved over time in response to political developments in the member countries; the development divide among the members, thus achieving a consensus to identifying and eliminating the NTBs can be a long drawn-out process; and supply-side capacity constraints.
