President Mohammed Shahabuddin and Prime Minister Sheikh Hasina on Sunday extended "heartfelt congratulations" to the President-elect of Maldives Dr Mohamed Muizzu.
They hoped to strengthen the bond between the countries in the coming days, the foreign ministry said in X, formerly known as Twitter.
Pro-China candidate Mohamed Muizzu won Saturday's presidential election in the Maldives, a result set to once again upend the archipelago's relationship with traditional benefactor India.
Muizzu, 45, helms a party that presided over an influx of Chinese loans when it last held power in the atoll nation, better known for its luxury beach resorts and celebrity tourists.
He won 54.06% of the vote in the run-off contest, prompting incumbent Ibrahim Mohamed Solih to concede defeat shortly before midnight.
The result upends Solih's efforts to revert the country's diplomatic posture back towards New Delhi since taking office five years ago.
Muizzu played a pivotal role in an earlier government's development program, bankrolled in part by financial largesse from China's Belt and Road infrastructure initiative.
He told a meeting with Chinese Communist Party officials last year that his party's return to office would "script a further chapter of strong ties between our two countries."
