VLADIVOSTOK, Russia — Secretary of State Hillary Rodham Clinton pledged Saturday that the United States would soon lift cold-war-era trade sanctions on Russia, but she did not address human rights legislation in Congress that has so far stalled passage, infuriated the Kremlin and become an unexpected issue in the American presidential race.

Attending the annual Asia-Pacific Economic Cooperation summit meeting here in place of the campaigning President Obama, Mrs. Clinton welcomed Russia’s accession to the World Trade Organization last month. And she said that the United States must now normalize trade relations so that American businesses can reap the benefits of Russia’s membership, including lower tariffs for American products.

Although the sanctions included in the 1974 law known as Jackson-Vanik are waived each year and have no practical effect, they violate W.T.O. rules, which could allow Russia to retaliate against American businesses.

The effort to grant Russia normal trade status, however, has become entangled in legislation that would punish Russian officials accused of abusing human rights, denying them visas and freezing their assets. That has raised doubts that any agreement on lifting the Jackson-Vanik provisions can be reached before the November election.
