The European Tour launched the new matchplay event between Asia and Europe last month after removing its sanction from the Royal Trophy, a similar matchplay tournament which had been launched by Ballesteros in 2006.
Ballesteros' brother Vicente has criticised the new event, and in particular the claim by European Tour chief executive George O'Grady that the Ballesteros family had lent their support to the venture.
Vicente Ballesteros said in a statement: "I am certain that Seve would have found this proposal to be in very bad taste and very disrespectful.
"Mr O'Grady has also said that this new proposed event is supported by the Ballesteros family. Whenever anyone talks in public about any family, that person must be very careful.
"I wonder what he means. My brother Baldomero and I do not support this new proposed event at all."
