Governments of the G‑20 could agree that until at least, say, December 2010 they would pledge:
- No increases in any MFN applied rate of duty other than for technical adjustments (completion of HS transpositions, for example).
- No increases in any Customs fees, excise duties applying to imports, consumption taxes applying to imports.
- No preliminary determinations of anti-dumping duties (and therefore, no new final duties either) or acceptance of new undertakings (if you want to stimulate consumption…).
- No safeguard action will be renewed, no new safeguard action will be available for more than 3 months
- No new export subsidies in any form (as defined by the Hong Kong Ministerial declaration).
- No new buy-local preferences at any level of government for goods or services contracts. Existing Government Procurement Code provisions (including exceptions) apply but Non-Members to be treated as Members (MFN provision).
- No new export restrictions (measures now in force—mainly security based—may remain in force)
Would this work? Yes, I think so. Should they do it? Yes, absolutely.
Would they sign it? Given that the G‑20 includes governments such as India that apparently hold the right to take safeguard action as sacred, and the United States (and Australia) that hold nearly the same view on anti-dumping, and Russia that is not yet a member of the WTO, the question is, at best, open.
