Taiwanese smartphone manufacturer HTC has doubled handset sales on year so far, helped largely by its partnership with mobile operator Chunghwa Telecom, ensuring that the company will surpass sales of its biggest rival Nokia and make it the top handset vendor in the country within the first half of the year.

Jack Tong, Vice President of Asia Pacific said that HTC’s handset sales in Taiwan in the first quarter have already reached half of the companys total handset shipments shipped in 2010, adding that sales in the Asia Pacific market have experienced growth at similar rates.

With Nokia holding top spot in terms of sales volume in the local market, Tong notes that HTC outperformed its rivals in December, becoming the number one vendor in terms of sales value. The company hopes to surpass Nokia’s sales volumes by July of this year.
