Iran leads the list of countries that have failed to crack down on money laundering and terrorist financing, the Financial Action Task Force, a global standard-setting body, said Thursday.

The task force, based at the Organization for Economic Cooperation and Development in Paris, reiterated a recommendation from last year that its members apply “effective countermeasures to protect their financial sectors from money laundering and financing of terrorism risks emanating from Iran.”

The task force did, however, welcome the fact that Tehran had recently started to “engage” with it. The moves appear to be mainly symbolic, however, as many countries have already taken steps to limit their companies’ economic exchanges with Iran.

The announcement was made at the same time that moves are afoot at the United Nations, led by Washington, to apply tougher sanctions against Tehran over its nuclear program. China, a major importer of Iranian oil, has so far appeared reluctant to agree to impose stiffer sanctions.
