"We are pursuing with the Swiss authorities and after our persuasion they have agreed to discuss and begin the negotiations on the amendment of the avoidance of double taxation agreement in respect of the exchange of information.

Switzerland had last week reached an agreement with the US to give that country's Internal Revenue Service details of 4,450 clients who Washington suspected of evading taxes.
