Russia is consulting with its allies about challenging the choice of Ajay Banga, the US nominee to head the World Bank, Moscow’s top representative at the bank said on Tuesday, a move that could complicate what was expected to be a smooth succession process.

Russia remains a voting member of the World Bank, although the bank halted all programmes in Russia and Belarus last March, citing what it called “hostilities against the people of Ukraine” following Russia’s invasion.

Roman Marshavin, the World Bank executive director who represents Russia and Syria, told Reuters the “listing of potential candidates and consultations are still ongoing”, but gave no details.

He said the decision would be made in Moscow. Russia’s plans were first reported by Russia’s state owned TASS news agency. It quoted Marshavin as saying he was in discussions with other countries about possible candidates, including Russian financiers and foreign economists, former heads of international organisations, as well as several ex-ministers of finance and heads of central banks.

Marshavin declined to comment on the specifics of the TASS report or which other countries were involved. US President Joe Biden last month nominated ex-Mastercard chief executive officer Banga, 63, to replace David Malpass at the helm of the World Bank, which oversees billions of dollars in funding for developing countries.

Banga, who is traveling in Africa, last week said he had already won support from India, Ghana and Kenya. He also got positive reviews from France and Germany at last month’s meeting of the Group of 20 finance officials, and on Tuesday won the endorsement of Bangladesh. The US treasury declined comment on the possible Russian challenge. While the bank will accept nominations from other countries until March 29, Biden’s nomination all but assures that Banga will fill the role.

The World Bank has been headed by someone from the United States, the lender’s dominant shareholder, since its founding at the end of the World War II.
