PARIS (Bloomberg) French President Nicolas Sarkozy said he doesn't rule out that Switzerland might be placed on a list of uncooperative tax havens being drawn up by the Organisation for Economic Cooperation and Development.[

Sarkozy and other European leaders from the Group of 20 nations a week ago said they will crack down on tax havens as they seek to boost transparency and apply uniform rules governing financial markets in the wake of the global economic crisis. They called for "sanctions" against "uncooperative jurisdictions".

The issue will discussed at a full G-20 meeting in London in April. The G-20 is comprised of both industrialised countries and developing nations including China, India and Brazil.Funds held offshore by individuals or companies to evade taxes or escape from political instability in their home countries is "somewhere between $5 trillion and $7 trillion", according to OECD Secretary General Angel Gurria.

The Paris-based OECD, which currently names Andorra, Monaco and Liechtenstein as uncooperative tax havens, is preparing a new "black list".Asked at a press conference in Brussels today whether Switzerland would be considered an uncooperative tax haven, Sarkozy answered that "based on the actual state of things and on the rules, it could be yes".

The French leader was speaking after a summit of EU leaders. In a position paper for discussion at last week's meeting in Berlin, Steinbrueck said the G-20 should take "concrete measures" against "uncooperative or non-transparent jurisdictions".The new OECD list, together with proposals for retaliation, is scheduled to be ready in May or June.
