DOHA - Gan Lin ran away with his second gold medal as China maintained their awesome showing in the Asian Games shooting on Wednesday, adding three more titles to their already impressive collection.

China's unceasing momentum in their build up to the 2008 Beijing Games has netted them 22 of the 32 gold medals decided so far, just five adrift of their tally in Pusan four years ago with two more days of competition remaining.

Gan, 23 and a world championship silver medallist, annexed the 10 metre running target mixed title for his second victory in the running target division in Doha.

Kazakhstan's Bakhtiyar Ibrayev took silver after helping his nation claim the team gold medal as a confident China failed to field a team in the event.

Hosts Qatar took a creditable silver in the team event, their fourth medal from the range, while Vietnam were third.

Gan's compatriot Wang Chengyi exacted sweet revenge over her experienced Kazakh rival Olga Dovgun to clinch a golden double in the women's rifle three-position event.

The 23-year-old Athens Olympic bronze medallist trailed Dovgun by a point entering the final but produced a superb 10-shot sequence to add another gold to the team title she won with Liu Bo and Wu Liuxi.

"I was ready mentally to do the best," Wang said.

Dovgun, who upstaged Wang for the rifle prone gold medal, claimed silver after helping Kazakhstan to the team bronze behind South Korea.

"A silver medal is very good for my country and myself, it is second to gold," said the 36-year-old mother of two.

It was Dovgun's fifth medal in Doha, taking her personal Asian Games tally to 10. Husband Vitaliy boosted the family haul with another three after claiming bronze in the rifle prone event.
