The International Religious Freedom Act was meant to put muscle behind America's push for religious rights around the world.
Today President Bush marked the 10th anniversary of the act.
"This legislation that we commemorate today builds on a tradition that defined our nation. After all, when the Founding Fathers adopted the Bill of Rights, the very first liberty they enshrined was the freedom of religion," Bush said.
He noted great progress in many nations, but also persecution of religious believers in quite a few others.
Bush gave several examples of Christians, Muslims, Buddhists and other believers still persecuted in lands such as Iran, Saudi Arabia, Myanmar , and China.
