We are delighted to place this first supplement before the readers of Merger Control Worldwide. Early in 2004 and well in advance of the day on which we began turning into reality our idea of preparing an ‘Encyclopedia’ covering merger control regimes around the world, we had planned supplements to bridge the time gap between the first and second editions of the work. At the relevant time, we left it open whether such supplements would be annual or biennial. Indeed, we contemplated opting for the former only if Merger Control Worldwide received a sufficiently warm welcome and provided that recent developments in different regimes would merit it. We are pleased that that has turned out to be the case and that we are able to produce this first annual supplement. More importantly, however, we are pleased to be able to include two new chapters covering South Korea and Mexico – jurisdictions that we had intended to include in the first edition but unfortunately were unable to do so at the time.

This supplement does not cover all the jurisdictions included in the first edition. In the case of most jurisdictions, no important developments have occurred over the past year. It is envisaged that jurisdictions that have not been included in this supplement will be included in the second supplement next year, should they witness any interesting and important developments.
