U.S. Secretary of State Hillary Clinton arrived in Mongolia Monday as part of an Asian tour aimed at promoting democracy, as local politicians were locked in dispute over recent elections.

Mongolian President Tsakhia Elbegdorj has called on all parties to agree on forming a ruling coalition, after official results showed the opposition Democratic Party won most seats, but not enough for a majority.

The U.S. government is suing to force an auction house to return the fossil of a dinosaur that roamed Mongolia 70 million years ago to the Asian country.

The nearly complete Tyrannosaurus bataar is believed to have been unearthed between 1995 and 2005, and is one of several specimens first discovered in the Gobi desert in 1946.

The fossil of a dinosaur that roamed the earth 70 million years ago should be turned over to the United States by an auction house so that it can be returned to its home in Mongolia, a lawsuit brought by the U.S. government demanded Monday.

The nearly complete Tyrannosaurus bataar skeleton was imported from Great Britain to Gainesville, Fla., in March 2010 with erroneous claims that it originated in Great Britain and was worth only $15,000, according to the lawsuit filed in U.S. District Court in Manhattan.

The giant dinosaurs that roamed the world some 150 million years ago shared the planet with equally daunting parasites: blood-gobbling fleas that were up two centimeters long.

So say Chinese and French paleontologists, who have pored over nine extraordinary fossils unearthed from Inner Mongolia and Liaoning province.

Ethnic demonstrations in Inner Mongolia will be handled according to the law and the government will respond to "reasonable demands" from protesters, a Chinese government spokeswoman said Tuesday.

In the 13th century, Mongol emperor Kublai Khan and his harem sported silk gowns, fur cloaks and jewel-encrusted head ornaments at their home -- the legendary pleasure palace in Xanadu.

Today, latter-day khans are again stepping out in some of the world’s finest luxury fashions as Mongolia’s minerals-fuelled economy boosts disposable income for the country's nouveaux riches.
