The head of Bangladesh's interim government, Nobel laureate Muhammad Yunus, said on Thursday that his country's high growth under ousted Prime Minister Sheikh Hasina was "fake" and faulted the world for not questioning what he said was her corruption.

Yunus, 84, an economist and the 2006 Nobel Peace Prize winner, took charge of the South Asian country's interim government in August after Hasina was forced to flee to neighbouring India following weeks of violent protests.

Hasina has been credited with turning around the economy and the country's massive garments industry during her 15 years in power, although critics have accused her of human rights violations and suppressing free speech and dissent.

Hasina, who had ruled Bangladesh since 2009, is being investigated there on suspicion of crimes against humanity, genocide, murder, corruption and money laundering and Dhaka has asked New Delhi to extradite her.

Hasina and her party deny wrongdoing, while New Delhi has not responded to the extradition request.

"She was in Davos telling everybody how to run a country. Nobody questioned that," Yunus told Reuters in an interview on the sidelines of the World Economic Forum's annual meeting in the Swiss Alpine resort. "That's not a good world system at all."

"The whole world is responsible for making that happen. So that's a good lesson for the world," he said. "She said, our growth rate surpasses everybody else. Fake growth rate, completely."

Yunus did not elaborate on why he thought that growth was fake, but went on to stress the importance of broad-based and inclusive growth, and the need to reduce wealth inequality.

Annual growth in the Muslim-majority country of 170 million people accelerated to nearly 8% in the financial year 2017/18, compared with about 5% when Hasina took over in 2009, before the impact of COVID-19 and the war in Ukraine pulled it down.

In 2023, the World Bank described Bangladesh as one of the world's fastest-growing economies.

"Since its independence in 1971, Bangladesh has transformed from one of the poorest countries to achieving lower-middle income status in 2015," it said.

HURT BY STRAINED INDIA TIES

The student-led movement in Bangladesh grew out of protests against quotas in government jobs that spiralled in July, provoking a violent crackdown that drew global criticism, although Hasina's government denied using excessive force.

The student protesters recommended Yunus as the chief adviser in the interim government tasked with holding fresh elections.

Yunus, who has promised to hold elections by the end of 2025 or early 2026, said he was not interested in running.

Known as the "banker to the poor", Yunus and the Grameen Bank he founded won the Nobel for helping lift millions from poverty with tiny loans of less than $100 offered to the rural poor, too poor to gain attention from traditional banks.

"For me, personally, I'm not very driven by growth rates," Yunus said. "I'm driven by the quality of life of the people at the very bottom level. So I would rather bring an economy which avoids the whole idea of wealth concentration."

Ties between Bangladesh and India, who have strong trade and cultural links, have become fraught since Hasina was ousted and she took refuge in New Delhi.

Yunus has demanded that India send Hasina back to Bangladesh so she can face trial for what it says are crimes against protesters and her opponents, and crimes she is accused of committing during her tenure.

Calling India's rival China a long-term friend of Bangladesh at this difficult time, Yunus said the strained relationship with New Delhi "hurts me a lot personally".

"Bangladesh-India relationship should be the strongest possible. You know, you cannot draw the map of India without drawing the map of Bangladesh," he said, referring to how Bangladesh's land border runs almost entirely alongside India’s.
