With the biggest prizes in badminton already in his trophy cabinet, Chen Long will now go in search of those still missing from his CV - including the OUE Singapore Open.

The reigning Olympic men's singles champion will spearhead a 23-strong Chinese team at the April 11-16 Superseries event.

In three previous appearances at Singapore's biggest badminton tournament, the 28-year-old's best showing was a quarter-final spot last year.

The world No. 5, a two-time world champion, has been been taking an extended break and has not played on the Badminton World Federation (BWF)'s professional circuit since the end of November.

"Everyone goes into a competition hoping to win and I am no different," said Chen, who is slated to return to competition at the end of the month at the German Open.

"I want to do my best to thank the fans who have been supporting (us) at the (Singapore) Indoor Stadium."

China's top women's singles player, world No. 4 Sun Yu, will also make the trip here. The 22-year-old won the title in 2015.

They will be joined by some in-form team-mates in the doubles.

World No. 1 mixed doubles pair Zheng Siwei and Chen Qingchen, as well as Zhang Nan - the reigning Olympic men's doubles champion with Fu Haifeng - are also in the Chinese squad.

Zhang will pair up with Liu Cheng in the men's doubles and partner Li Yinhui in the mixed doubles. He just lifted the Thailand Masters trophy with Li over the weekend.

The Chinese team are expected to face stiff opposition from South Korea, who are also sending their big guns.

Men's world No. 4 Son Wan Ho and women's No. 3 Sung Ji Hyun will lead the South Koreans' title charge.

They will be joined by Olympic women's doubles bronze medallists Jung Kyung Eun and Shin Seung Chan.

The Chinese and South Korean squads join an already stellar cast of shuttlers who have confirmed their participation.
