Nissan Motor Co. said Wednesday it logged a record-high group net profit of ¥452.84 billion for the April to December period as strong sales in North America and Western Europe more than offset weakness in emerging markets and at home.

The figure marked a 33.7 percent rise from a year earlier. Consolidated operating profit increased 40.6 percent to ¥587.54 billion on sales of ¥8.94 trillion, up 10.6 percent.

"Strong sales of our new models, the momentum we have seen in North America and Western Europe and our continued efforts to boost cost efficiency can outweigh sluggish sales in emerging markets and unstable currency moves," Nissan Corporate Vice President Joji Tagawa told a briefing.
