The Asia-Pacific 'super series' has been rocked after the Japan Golf Tour Organisation (JGTO) slammed the organisation surrounding the event.
It cited the Asian Tour's absence from being involved in the programme as the key reason behind its decision to pull out.
The JGT believes the Asian Tour's participation is "imperative and necessary".
It also stated concerns such as other member tours' status, the conditions of JGTO golfers' planning conditions and marketing and broadcasting arrangements.
PGA Australia last week announced details of the series which has been supported by the China Golf Association and the Korea Golf Association.
Although initially in support of the programme, the JGTO's opposition follows criticism from Asian Tour officials.
The series is expected to start with the China Open on April 16th.
If the JGTO does take part, 17-year-old sensation Ryo Ishikawa could feature.
The youngster, who is currently ranked 60th in the world, is set to make his PGA Tour debut at the Northern Trust Open next month and has been invited to the US Masters in April.
