The World Water Summit, to start in Budapest on Tuesday, will attract participants from a record 118 nations, the chief organiser told MTI. Over 30 ministerial delegations, head of international organisations and multilateral financial institutions and water experts will discuss ways to prevent a global water crisis, Istvan Joo, state secretary at the foreign ministry, said on Monday. The three-day summit will be accompanied by 16 fringe events, including an exhibition with Hungarian innovations expected to play a key role in preventing the crisis.
