Following Dyson Ltd.'s plans late last year to manufacture its first electric car in Singapore, the city-state is now in talks with other makers of green vehicles to set up shop on the island.

Singapore is pitching its connectivity to global markets through free-trade agreements, its high-skilled workforce and stringent protection of intellectual property, which is critical for the industry, according to the government agency set up to attract investments to the country.

"Hopefully they won't be the only one we land," Chng Kai Fong, managing director of the Singapore Economic Development Board, said in an interview, referring to Dyson's plans. "We're in active negotiations or discussions with a couple of others. The whole idea is to build clusters."
