Amends the Trafficking Victims Protection Act of 2000 to declare that, in determining whether a government has made serious and sustained efforts to reduce the demand for commercial sex acts and participation in international sex tourism by its nationals, pursuant to the minimum standards for the elimination of sex trafficking, if such government has the authority to prohibit the purchase of commercial sex acts but fails to do so, it shall be deemed a failure to make serious and sustained efforts to reduce the demand for commercial sex acts, notwithstanding other efforts the government has made to do so.
