The volume of overall investment  is expected to top $45 billion over five years in Bahrain, a top businessman said.
Citing figures released in the Unified Arab Economic Report, he said that public sector investments are expected to average 40 per cent between 2013 and 2017.
Private sector and foreign investments  are predicted to make up the rest.
"These reassuring indices represent a vote of confidence for the investment environment in all sectors," Bahrain Chamber of Commerce and Industry chairman Dr Essam Fakhro said.
He said industries, higher education, training institutes, and health and financial services are the key sectors that will attract investment.
The next five years also augur well for transport, logistics services, information technology, family tourism, aluminium byproducts and project management, Dr Fakhro said.
He hoped all sectors would be revitalised this year, and promised that the chamber will play a bigger role in strengthening Bahrain's trade and economy.
