Tunisia's prime minister has called for greater foreign investment to help support the country's ailing economy and the transition to democracy.

In a conference entitled "Investment in Tunisia: Startup Democracy," Prime Minister Mehdi Jomaa on Monday called "investing in Tunisia an investment in democracy."

Tunisians overthrew their dictator in 2011 and are set to complete the democratic transition with autumn elections.

The economy is failing, however, with 15.7 percent unemployment. Some 15 percent of the population lives under the poverty line, up from 10 percent in 2010, according to recent central bank figures.

Bank head Chadli Ayari said growth for 2014 is predicted to only be 2.8 percent, while inflation is at 7 percent.

The conference was attended by representatives of 30 countries, including French Prime Minister Emmanuel Valls.
