There is an interesting ranking of the WTO-citizenship of member states available from the WTO summer program at the HEI .
Guess who's #1? (hint: not Singapore or HK, the usual suspects for die-hard free traders).
Several CIS states and middle-eastern states score very high in the ranking, and there is even an LDC (Lesotho) in the top 10, while Moldova is #1 for services.
The complete methodology is as explained here:
The methodology of the agricultural and industrial rankings were based on the level of bound and applied tariffs. As many members cannot afford extensive subsidies they were not deemed a helpful determinant, low levels of subsidy could just be a consequence of budgetary constraint rather than intention. Services and contingency protection rankings were made on the basis of the number of notifications the particular country had made in respective committees.
