The US bourse is set to open higher as European leaders get ready to meet.

New York - US stocks moved higher in early trade Tuesday as markets shrugged off Russia's move to formally absorb Crimea and began turning attention to a US Federal Reserve monetary policy meeting.

About 35 minutes into trade, the Dow Jones Industrial Average rose 67.23 points (0.41 percent) to 16,314.45.

The broad-based S&P 500 jumped 7.55 (0.41 percent) to 1,866.38, while the tech-rich Nasdaq Composite Index increased 22.48 (0.53

percent) to 4,302.43.

Russian President Vladimir Putin signed a treaty making Crimea part of Russia, moving quickly after Sunday's referendum in Crimea overwhelmingly endorsed integration into Russia.

The move heightens tensions between Ukraine and the West. But Putin also said Russia had no designs on a larger break-up of Ukraine.

Markets treated the latest Ukraine developments as consistent with expectations.

“We'll see how Mr. Putin's position plays out in Washington, but Wall Street for one looks eager to take the Russian spin on Ukraine matters at face value,” said analyst Patrick O'Hare.

Meanwhile, investors also were shifting their gaze to the Fed, which will kick off a two-day meeting of the Federal Open Market Committee later Tuesday, culminating with Wednesday's policy statement and a news conference with Fed Chair Janet Yellen.
