Officials in Pakistan, which does not hold beauty pageants, said Thursday they were investigating how Texas-based Mariyah Moten, 22, entered a "Miss Bikini" pageant in China last month as a Pakistani contestant.

Pakistan-born Moten, who holds an American passport, won a "Best in Media" title for being the most photographed and interviewed contestant, media reports said.

"I have broken all the barriers, and in the coming years there will be other Pakistani contestants who will carry this title," Moten, described by Pakistani media as the country's first bikini queen, told the Times of India newspaper.

"My intention was to project Pakistan in a very modern way."

Moten was born and brought up in the Pakistani city of Karachi. Her family moved to the United States eight years ago and she is now based in Houston.

Pakistani authorities said they might take up the issue with China, and might also withdraw from Moten privileges offered to people of Pakistani descent such as visa-free travel to Pakistan.

Moten, who said she might consider a career in the Pakistani film industry, was undeterred by the criticism.

"The hardliners are basically people who impose their thoughts on others, and we are not affected by people like them.

"It is actually very amusing how they are always so ready to react," the daily quoted her as saying.
