Mr McDouall said council was reviewing it's sister city strategy and that the nature of sister cities was changing.
"It's the start of a process. This is not speed dating," Whanganui mayor Hamish McDouall said.
"The days of these being a cultural exercise are long gone. Really, there needs to be a mutual benefit and particularly and economic benefit."
He said Namdong Gu was a port district of Incheon.
"So there's quite a bit of potential there for cross-pollination. Also it's a city which is quite proud of it's aged care."
