PARIS -- The OECD said on Tuesday that the four countries on a tax haven blacklist, published as part of agreements at last week's G20 summit, have committed to meeting international standards and will be removed form the list.

Last Thursday, the Organization of Economic Cooperation and Development placed Uruguay, Costa Rica, Malaysia and the Philippines on the blacklist as part of efforts agreed at the Group of 20 leaders summit to crack down on tax evasion.

The OECD published three lists -- black, grey and white -- which respectively identify the worst offenders, those that are somewhere in-between, and those who are considered as fully committed to internationally acceptable standards.

The removal of the four countries from the blacklist was announced in a statement and at a news conference where OECD chief Angel Gurria said:

"This very important move by so many jurisdictions ... is one of the first deliverables of the G20 meeting."

He was referring to the G20 summit of world leaders which last week asked the OECD to publish the blacklist in a renewed move to crack down on tax fraud across the globe.
