Mauritius has a number of excellent DTA treaties.  These treaties not only reduce or eliminate the effects of double taxation, but can be advantageous in reducing withholding taxes on royalties, dividends and interest.  They can also eliminate or reduce the effects of capital gains tax.  Each treaty is different but most tend to follow the OECD format.  This makes treaty comparison a lot simpler as terminology, approach and layout are standardised.
