According to Norson Telecom Consulting, the six best-selling GSM mobile phone models in the third quarter of 2005 in China were all made by Nokia.
And Giles said two out of the three best-selling CDMA mobile phone models last year were Nokia's.
Fancy mobile phones with digital cameras and music players will continue to spur growth in the Chinese market, he said.
"Replacement mobile phone sales will represent 60 per cent of the total market this year," he said.
Nokia last year launched more than 30 mobile phone models in China, half of which have built-in MP3 music players.
The rural market, where consumers are buying mobile phones for the first time, is also providing Nokia with opportunities, said Giles.
Nokia will this year try to push into the enterprise sector by aggressively promoting its high-end models to corporate users, the vice-president said.
"The enterprise sector remains an untapped area in China," he said.
Mobile phones that offer faster e-mail and Internet access are not yet as popular in China as in Western countries.
