Hoang Xuan Vinh has become the first ever Vietnamese shooter to win an official Olympics berth.
Vinh won 682.4 points in the men's 10-meter air gun event on Monday at the January 11-22 Asian Shooting Championships in Doha, Qatar.
Vinh finished fourth behind the gold medal winner from South Korea, Jin Jong Oh with 689.6 points, silver medalist from China, Wang Zhiwei with 683.1 points and Japanese bronze medal winner Matsuda Tomoyuki with 682.7 points.
However, the 37-year-old Vinh won an Olympic berth because the other three medalists had already qualified for the London Games before.
Vietnamese shooters have been given berths at previous Olympic Games but they were only wild card entries for countries underdeveloped in sports.
Vinh is the eighth Vietnamese athlete to have won a London Olympics berth.
The other seven athletes are female judo martial artist Van Ngoc Tu, male badminton player Nguyen Tien Minh, female taekwondo martial artist Chu Hoang Dieu Linh and male taekwondo martial artist Le Huynh Chau, male gymnast Pham Phuoc Hung, female gymnast Phan Ha Thanh and male swimmer Hoang Quy Phuoc,
Vietnam has set itself a target of winning 25 Olympic berths including wild card entries.
