Donald Trump’s pick for World Bank president, David Malpass, has officially been approved for the role.
Mr Malpass, a Trump loyalist, was a senior economic adviser to the US president during his 2016 election campaign.
His appointment has stirred debate, as some worry that Mr Malpass, a critic of the bank, will seek to reduce its role.
In February White House officials said Mr Malpass, a long-time Republican, would be a “pro-growth reformer”.
Mr Malpass said he was “honoured” by the appointment.
“Our twin goals of eliminating extreme poverty and achieving shared prosperity are more relevant than ever,” he said.
The former Bear Sterns economist has criticised the World Bank in the past, along with other multilateral institutions such as the International Monetary Fund (IMF), for being “intrusive” and “entrenched”.
‘Not willing to fight’
To become World Bank president Mr Malpass won unanimous approval from the institution’s executive board, which has 25 members.
The US holds a 16% share of board voting power and has traditionally chosen the World Bank’s leader.
China is the World Bank’s third-largest shareholder after Japan, with about a 4.5% share of voting power.
Professor Christopher Kilby, an expert on the economics of foreign aid at Villanova University near Philadelphia, said it is likely that China and other shareholders did not push back on Mr Malpass’ appointment as they “recognise that they are unlikely to succeed in derailing the US nominee.”
“Since they have seen President Trump punish those who stand up to him, they are not willing to fight the US,” Prof Kilby said.
In the past China has also not sought more power within the World Bank as some of its aims, including promoting the rights of indigenous peoples, do not align with Chinese domestic and foreign policy, Prof Kilby said.

David Malpass will need to establish his credibility quickly as the new president of the World Bank.
The legitimacy of the selection process came under renewed scrutiny after Donald Trump’s pick emerged as the only candidate to succeed Jim Kim.
And he’s been an outspoken critic of the institution he’s about to lead.
In the past, he’s described the World Bank as too big. He’s said he’d like to lend less to middle income countries like China, which he argues are financially strong enough. And he has challenged the global order.
Speaking at an event at the Council on Foreign Relations back in 2017 he said:
“Multilateralism has gone substantially too far – to the point where it is hurting US and global growth”.
But while past statements offer a glimpse of some of his thinking, they don’t tell the full story.
When his predecessor Jim Kim asked shareholders for more money, it was David Malpass who – in exchange for reforms at the bank – helped make it happen.
And since being nominated for the position, his tone has softened.
Will he be able to articulate a vision for the bank to win over doubters?
The World Bank critic could narrow the focus of its lending to the world’s poorest countries, among other changes.
He has pushed for the World Bank to halt lending to China, which he says is too wealthy to deserve such aid.
And last year, he was part of negotiations over a package of World Bank lending reforms.
The US agreed to back a plan for shareholders to inject $13bn (£10bn) into the World Bank and its private lending arm, with conditions that aimed to limit the bank’s lending, and focus resources more on poorer countries.
The reforms are aimed at pushing more middle-income countries towards private sector lending, and limiting World Bank staff salary growth.
Controversial US picks
Traditionally, the US picks the World Bank president, Europeans choose the IMF managing director, and the Japanese do the same for the Asian Development Bank.
Prof Kilby said a more controversial US pick for the World Bank president role was neoconservative Paul Wolfowitz, and yet he still landed the role.
Mr Wolfowitz, who had the job between 1 June 2005 and 30 June 2007, was seen as a driving force behind pursuing the US-led conflict in Iraq.
“For this and other reasons, Mr Wolfowitz was unacceptable to the Europeans and there was push back, including other nominees, for a while,” Prof Kilby said.
“But as the election date drew near, the fear that this would threaten the European traditional right to pick the head of the IMF led the European countries to back down and accept the US pick,” he added.
