Racially-motivated hate crimes occur frequently in the US, and sufferings of the civil rights activists in the nation have aroused attention, said the Human Rights Record of the United States in 2011 released by China on Friday.

Citing an FBI report, the report issued by the State Council Information Office of the People's Republic of China said 6,628 hate crime incidents were reported in 2010, 2,201 of which were against African Americans, 534 against Hispanics, and 575 against whites.

Among the cases, 47.3 percent of all were motivated by racial bias, 20 percent by religion, and 12.8 percent by an ethnicity/national origin bias.

According to a report released by the Center for American Progress in August, 2011, seven American charitable groups, over the past decade, had spent 42.6 million U.S. dollars on inciting hatred against Islam communities, said the document.

The report also mentioned the status of civil rights activists in the U.S., who oppose racial discriminations. It said the sufferings of the activists "arouse attention."

Citing report carried by The Huffington Post, it said, Catrina Wallace, a civil rights activist in Jena, Louisiana, was sentenced to 15 years in prison by authorities only based on a drug dealer's accusation.

According to The Huffington Post, Wallace had previously taken part in organizing a 50,000-people protest against racial discrimination that won freedom for six black high school students, and the article deemed the sentence was a "revenge taken by authorities on Wallace's human rights activism."
