The president of the World Bank, Robert Zoellick, criticized Argentina’s plans to nationalize its largest oil company.
Addressing a news conference in Washington on Thursday, Zoellick cautioned policy makers against moves based on populism and protectionism that could hurt the economy.
“I think it’s a mistake, and I think it’s a symptom that we have to watch out for . . . , ” he said.
The Argentine government announced plans earlier this week to take over YPF, an Argentine unit of Spain’s Repsol.
The government said the move was intended to boost oil output. Spain has sharply criticized the plan.
