Foreign investments in Tunisia grew by 17.7 percent in the first half of this year, Tunisian Minister of Investment and International Cooperation Zied Laadhari said on Tuesday.

"The government is currently promoting investment potentials in different regions of the country," said Laadhari.

"Nowadays, it will be necessary to achieve equal opportunity for development in all regions of the country," the official said.

Laadhari announced that a high-level global conference, to be held in Tunis in September, will unveil over 20 public-private partnership projects.
