The United States and Singapore signed an agreement Wednesday to “deepen” cooperation on the peaceful use of nuclear energy as the city-state considers alternative power sources to cut carbon emissions.

Singapore, a regional financial centre and a key player in the global semiconductor industry, is currently reliant on oil and natural gas.

It is studying options, including nuclear power, to meet its target of net-zero carbon emissions by 2050.

The agreement is expected to come into force by end-2024 after being reviewed by the US Congress, the statement said.
