Nissan said it is too early to say if it will spin off its electric vehicle business, as alliance partner Renault is seeking to do, Nissan Chief Operating Officer Ashwani Gupta said.
"It's too early to consider because of our diversified market portfolio and diversified product portfolio," Gupta said Friday.
Renault said in April that all options were on the table for separating its EV business, including a possible public listing, as it seeks to catch up with rivals such as Tesla and Volkswagen.
The move has also raised speculation that Renault may consider lowering its stake in Nissan. Renault owns 43.4 percent of Nissan, which in turn has a 15 percent non-voting stake in the French company.
The structure of the partnership has long been a source of friction in Japan.
As an alliance member, Nissan would support Renault's endeavors, Gupta told reporters. At the same time, Nissan needs to focus on both electric vehicles and internal-combustion engine cars that include the hybrids, he said.
Renault Group CEO Luca de Meo plans to meet with executives from Nissan and fellow alliance member Mitsubishi in Japan next week to discuss the proposal.
