Australian mining billionaire Andrew Forrest has launched a fund that is hoped to be worth at least $25bn (£21bn) to help rebuild war-torn Ukraine.
Mr Forrest and his wife have committed $500m to the fund, which its organisers say could eventually grow to $100bn.
The Ukraine Green Growth Initiative plans to invest in primary infrastructure such as energy and telecoms networks.
President Zelensky welcomed the move.
“We will take advantage of the fact that what the Russians have destroyed can readily be replaced with the latest, most modern green and digital infrastructure,” Mr Zelensky said.
