U.S. and Singaporean officials say radiation detectors will be installed in the city-state's busy ports to prevent smuggling of ingredients of so-called "dirty" nuclear bombs.
Officials from both nations signed a declaration of principles to deploy the equipment, making Singapore the first Southeast Asian country to install the specialized technology.
The agreement is part of a U.S. initiative aimed at detecting and intercepting illegal shipments of nuclear weapons materials before they reach American ports.
The devices resemble a gate that can sound an alarm when containers holding nuclear material pass through. U.S. officials say the equipment should be ready for installation by September.
Singapore, a staunch U.S. ally in the war on terror, operates one of the world's busiest ports.
