"Yes, there is a huge number (of Asian players), but if the LPGA Tour is going to remain home to the best women's golf in the world, the last thing you want to do is put quotas on it," Bivens told reporters during Thursday's opening round of the $2 million HSBC Women's Champions championship in Singapore.

"I am not concerned about Americans getting squeezed out.

"Do you want to have the best tour, do you want to have the most competition, do you want to have the highest level of performance? Or do you want to protect a nationality? We think we are doing both."

US players competing here in the HSBC Champions event at the Tanah Merah Country Club accounted for less than a third of the field while Asian players made up about 50 percent and Bivens said the growing influence of Asian players in the United States was welcomed by American players because they had raised the bar in terms of work ethic and performance.

"I don't think there are any Americans out there today who wouldn't say that Asians have made this tour better and more competitive," she added.

Bivans said the LPGA was working hard to overcome the challenges of limited exposure and media coverage, but she said she was convinced this could be achieved by attracting the world's best to the tour.

"If we have the most competitive tour in the world, we'll draw the best sponsors, we'll draw the most rabid fans and our media challenges will be lessened," she insisted.

"Performance is the very first standard that we have to uphold."
