Chinese shooter Hu Binyuan tipped India's Olympic silver medalist Si Rajyavardhan Rathore as his biggest threat as Olympic champion Ahmed Al Maktoum will be absent from the Asian Games.

"Though Al Maktoum is not coming, Rathore is also a dangerous opponent," the world runner-up in doubles trap said on Tuesday.

"But in the shooting sport, concentration is the most important and I won't let my guard down," added Hu, who won a gold medal in the 1998 Asian Games in Bangkok.

The 42-year-old Al Maktoum, who won the first ever Olympic gold for the United Arab Emirates, is a member of the ruling family of Dubai, and was once the UAE national champion in squash.

"It is really a pity, because he is a great shooter. He didn't compete internationally this year," said Sun Shengwei, head coach of the Chinese shotgun team, who just arrived here Tuesday afternoon with the Chinese delegation.

In the Busan Games four years ago, neither of China's three shooters made the podium in the men's double trap individual event and they were beaten to second place by South Korea in the team contest.

The shooting competition will be held from Dec. 2-8 at Lusial Shooting Complex, offering 44 gold medals.
