Switzerland, Luxembourg and Austria are fighting attempts to put them on blacklist for being tax havens and over-secretive in banking rules.

Luxembourg officials hosted discussions with the Swiss and Austrian finance ministers over the weekend, resulting in a demand for involvement in talks on the issue prior to the G20 summit next month.

Luxembourg treasury officials said the small European group wanted to be involved in the debates about bank secrecy which were currently being discussed in meetings to which they did not belong, such as the G20.

Concern is growing in Luxembourg, Austria and Switzerland about the international pressure on bank secrecy rules, with the G20 summit in London on April 2nd set to reveal a list of uncooperative tax havens.
