Vice President Venkaiah Naidu on Friday (local time) interacted with Indian community living in Serbia at the Beograd Hall inside Hotel Hyatt Regency in Serbia's capital Belgrade. The Vice President said, "The country is also allowing foreign direct investment in most of the sectors. And then the country has also moved to the PPP model - Public-Private partnership. Earlier we were guided by one philosophy that government will do everything, and private sector is not allowed." "But now the situation has totally changed, Public-Private partnership is now the order of the day," Naidu added. Venkaiah Naidu arrived in Belgrade on Friday. VP Naidu is on a three-nation visit. After Serbia he will be visiting Malta and Romania. Naidu is on a weeklong trip from September 14 -21. He is scheduled to interact with the heads of states of all the three countries and witness the signing of several Memorandum of Understandings (MOUs).
