A woman who bribed a top United Nations official to get support for business ventures has been sentenced to 20 months in prison.

Sheri Yan was sentenced Friday. The 60-year-old pleaded guilty in January.

She admitted paying more than $800,000 in bribes to former U.N. General Assembly President John Ashe, who died several weeks ago in an accident.

Ashe had pleaded not guilty to a tax charge in the case.

Manhattan federal Judge Vernon Broderick rejected defense lawyers' request to keep Yan out of prison. Prosecutors, meanwhile, sought a nearly six-year prison term.

The judge said some prison time was necessary because bribery schemes do substantial damage to the United Nations and its image.
