As per Wikipedia:

As of 1 January 2017, Mauritian citizens had visa-free or visa on arrival access to 131 countries and territories, ranking the Mauritian passport 33rd in terms of travel freedom according to the Henley visa restrictions index. As of December 2017, Grenada, Serbia, Seychelles and Mauritius are the only countries whose citizens may travel without a visa to China, Russia and the Schengen Area.

Mauritius does not have the bargaining power of European Union, it is not a superpower, it does not play an important role in global politics.

What gives it the edge? I know about visa reciprocity, but Mauritius needs some bargaining power.
