NRC said the memorandum currently has no financial implications for the council, but the possibility it might lead to some sort of investment opportunities in future could not be ruled out, Mr Shepherd said.
"One of council's roles is to advocate for economic development and attract investment and jobs into the region,'' he said.
"The MoU makes it easier for us to do this by providing potential Chinese investors with advice about who they should be talking to when they are looking at potential developments."
Regarding recent claims the council was part of secret negotiations concerning a private/public contract for the job to widen the highway from Whangarei to Marsden Point, Mr Shepherd said the NRC is not in the business of building roads, rail and other infrastructure.
There are other agencies and businesses at both local and national level which already do that, he said. District councils are responsible for local roads, while the NZ Transport Agency is responsible for state highways. KiwiRail is responsible for the rail network.
"The MoU simply outlines a proposed, high-level strategic relationship between ourselves and China Railway Zhongji Holding Group and enables us to maintain a warm, strong and mutually beneficial relationship," Mr Shepherd said.
