(ANSA-AFP) - OSLO, 20 MAR - Ukrainian President Volodymyr Zelensky on Thursday said he could not legally negotiate ownership of the occupied Zaporizhzhia nuclear power station, which President Donald Trump suggested Washington could take over. "We will not discuss it. We have 15 nuclear power units in operation today. This all belongs to our state," Zelensky said, adding he was open to talking about US investment once Ukraine got back the Russian-occupied plant. (ANSA-AFP).
