US Open champion Rory McIlroy and Masters winner Charl Schwartzel have confirmed their participation in this year's Omega Mission Hills World Cup, which will also see Italian brothers Edoardo and Francesco Molinari defend their title.

The event moves to the new Mission Hills Resort on Hainan Island from Nov 24-27, and Irishman McIlroy and South African Schwartzel, ranked third and 13th in the world are excited at the prospect of trying to lower the Italians' colors in China.

McIlroy has selected close friend and world No 15 Graeme McDowell, the 2010 US Open champion, as his partner. Schwartzel will team with Louis Oosthuizen.

Francesco Molinari, No 32 in the world, opted for brother Edoardo for Italy's challenge to retain its crown on Hainan Island.

Another reigning major champion, world No 6 Martin Kaymer, will represent Germany, hoping to emulate his country's victory in Barbados in 2006 when Bernhard Langer and Marcel Siem triumphed.

England's Ian Poulter and America's Matt Kuchar have also confirmed their intention to chase World Cup glory, and both will select their partners at a later date.

Sweden's Robert Karlsson, who partnered Henrik Stenson to victory at the original Mission Hills Resort in 2008 and finished joint runner-up with Ireland in 2009, is a confirmed participant once again, as are Alvaro Quiros of Spain, Scotland's Martin Laird, Anders Hansen of Denmark - who has selected Thomas Bjrn as his partner - Raphal Jacquelin of France, Brendan Jones and Richard Green (Australia), Nicolas Colsaerts and Jerome Theunis (Belgium), Camilo Villegas and his brother, Manuel (Colombia), and Jamie Donaldson and Rhys Davies (Wales).
