The PGA Tour Series-China has postponed four tournaments and two qualifying events because of concerns over the spread of the coronavirus.

The qualifying tournaments were scheduled for Bintan in Indonesia and Phuket in Thailand, with the event in Bintan having already been switched from Haikou in China.

It is hoped that the qualifiers can be played in late April or early May, with the regular season beginning in late May or early June.

The postponed tournaments are the Sanya Championship (March 23-29), the Haikou Classic (March 30-April 5), the Chongqing Championship (April 6-12) and the Guangzhou Open (April 13-19).

"We watched and scrutinised the situation closely and we did not make this decision lightly," PGA Tour Series-China executive director Greg Carlson said.

"After consultation with a variety of agencies, we determined postponement of the qualifying tournaments and the start of the regular season are the best courses of action at this time.

"This is a major international health issue, and we will do everything possible to ensure the safety and well-being of our players and everybody else associated with these two tournaments.

"We appreciate the patience our players have shown during what is a difficult time as they try to prepare for their seasons. At the same time, we don't want to do anything that might jeopardise the health of them or anybody else who is involved in PGA TOUR Series-China."

Earlier this week, LPGA tournaments in Thailand and Singapore were cancelled due to the ongoing situation.

The Honda LPGA Thailand, which was scheduled to take place from February 20-23 in Pattaya, and the HSBC Women's World Championship - due to be held in Singapore from February 27-March 1 - were called off.
