If elected President, "I will cut off funding for the United Nations Population Fund, which supports China's barbaric one-child policy," Romney said in his address to Conservative Political Action conference here.

Asserting that his presidency would be a pro-life presidency, Romney, the former Massachusetts governor, said he will ensure that organizations like Planned Parenthood get no more federal support.

"I will reverse every single Obama regulation that attacks our religious liberty and threatens innocent life in this country," he said.

"The presidency is more than public office. It's a sacred trust. As President, I will honor that trust by assuring that America remains the greatest military power on the face of the Earth. I will not be cutting our military budget," he said. 64-year-old Romney is considered a front-runner to bag the Republican nomination to challenge incumbent Barack Obama in November elections for US presidency.

"Today we really are poised for victory in November. The pundits and the pollsters are saying that we can win the election, but we have to tell the nation why we should win the election.

It's up to us to prove that we're really ready to step forward and lead this country," he said.
