PETALING JAYA: While many national shuttlers are using the Asian Championships in Ningbo, China, as a tune-up for the Thomas and Uber Cups, mixed doubles pair Chen Tang Jie-Toh Ee Wei are focused firmly on defending their world title.

The duo will not feature in the team event in Horsens, Denmark later this month, but their campaign in Ningbo, which begins today, marks a crucial step in building momentum towards the World Championships in New Delhi this August.
