The G20 Leaders Summits in London, Pittsburgh, Toronto, Seoul, Cannes and and Los Cabos requested UNCTAD and the OECD to jointly prepare regular monitoring reports on G20 countries' investment policy measures. Each report is issued together with a report on trade measures, prepared by the WTO, prefaced by a joint cover letter by the heads of the three organizations.
Thus far, the reports find that G20 countries have honoured their commitment to resist protectionism, but they call upon further vigilance in this regard.
- At the G20 Summit meeting in London in April 2009, G20 Leaders committed to forego protectionism and requested public reports on their adherence to this commitment on a quarterly basis; this was reaffirmed at their meeting in Pittsburgh in September 2009.
- At the G20 Summit in Toronto in June 2010, G20 Leaders renewed their commitment, until the end of 2013, to refrain, among other things, from raising barriers or imposing new barriers to investment or trade in goods and services, and to rectify such measures as they arise.
- At the G20 Leaders meeting in Seoul in November 2010 and in Cannes in November 2011, G20 Leaders reaffirmed the extension of their standstill commitment to resist protectionism until the end of 2013, and committed to roll-back any new protectionist measures that may have arisen. They asked the WTO to continue monitoring trade policy developments and UNCTAD and the OECD to continue monitoring investment policy developments and to report publicly on a semi-annual basis.
- Several G20 member countries reiterated this commitment at UNCTAD's Second World Investment Forum (WIF), held in September 2010, in Xiamen, China.
- In June 2012, G20 Leaders in Los Cabos expressed their concern about rising instances of trade and investment protectionism around the world and encouraged UNCTAD, OECD and WTO to reinforce and deepen their work in these areas.
The joint UNCTAD-OECD reports classify measures into: i) investment policy measures; ii) investment measures relating to national security; iii) emergency and related measures with potential impacts on international investment; and, iv) international investment agreements (IIAs). Information about the measures covered by the reports is collected from official and public sources. All information collected is sent for verification by G20 member countries.
