I am in contact with leaders and officials both from the world’s most developed nations and from developing countries. When the Doha Development Round talks collapsed in July, I was struck by the gap between what officials say when they meet at the OECD in Paris and how they define their positions in the WTO talks in Geneva.

Over the past 50 years, the world has seen unprecedented welfare gains. But these gains have been uneven, and progress indicators may mask absolute numbers that have actually become worse.

Is Africa finally on the move? The signs are promising.Rich in natural resources and with more than one billion people, it achieved five consecutive years of economic growth averaging more than 5% over 2004-08. In fact, private investment rose every year from 2000 to reach US$472.2 billion in 2008. And despite some fallout from the economic crisis that started in the OECD area in 2008 and brought African GDP per head to a virtual standstill in 2009, activity has started to ramp up again.

International trade fell off the charts in the fourth quarter of 2008 and showed only a modest easing in the rate of decline in the early months of 2009. Well-regulated open trade is essential for economic recovery and development, yet in times of crisis, protectionism may appear an attractive solution. It should be resisted.

As you point out, a key cause of the problems of the Doha trade round has been a lack of understanding among voters and opinion makers in the developed world on the importance of farm trade liberalisation (No 257, October 2006).

The Doha round of trade negotiations was launched in November 2001, but stalled in July this year. It should be relaunched. International trade may be stronger today than ever, but the global marketplace remains littered with barriers and restrictions that hold back potential, not least in developing countries.
