The Organization of Economic Cooperation and Development (OECD) is set to upgrade its outlook for world economy as a result of better-than-expected performances of some countries, the OECD chief said on Tuesday.

"It is probable that those nations will have numbers better than original projections," said OECD Secretary General Jose Angel Gurria, after presenting a report on Mexico's education system.

Gurria said economic stimulus packages worldwide have worked on job market and economic activities, citing positive signs from the United States, China and Japan.

He said OECD will adjust its forecast for global economy in the Economic Outlook, to be published on 24 June, but he did not say what's the new figure. OECD warned in March that the economies of leading developed countries would witness a likely contract of 4.3 percent this year.

"There has never been an economic crisis in which all the countries of the OECD are in recession at the same time," said Gurria, "This is happening at the moment."

The worst for Mexico is over now, he added, but indicators have not yet recovered and negative numbers probably last in the remainder of 2009.

Gurria noted that 2009 had been a very bad year and it would take years to return to the levels before the crisis.
