Both the agreements were signed in London, by Guernsey's treasury and resources minister Gavin St Pier and the high commissioner for the Seychelles Marie-Pierre Lloyd, and Guernsey's minister for commerce and employment Kevin Stewart and high commissioner for Mauritius, Abhimanu Kundasamy.
St Pier said: “Since 2011, Guernsey has worked closely with member states of the Southern African Development Community to support those countries' ability to protect their tax revenue. These two DTAs are further illustration of that work, which is in line with the development aims of many organisations, not least the G8 and the OECD.”
Stewart added that both Mauritius and the Seychelles have growing finance centres and as island jurisdictions share many of the challenges Guernsey faces.
"Both jurisdictions complimented us on our tax transparency leadership. We reiterated our message that transparency has strengthened our competitiveness,” Stewart said.
Guernsey’s 10 comprehensive DTAs are now with Hong Kong, the Isle of Man, Jersey, Luxembourg, Malta, Mauritius, Qatar, Seychelles, Singapore and the UK.
