The government officially promotes racial and ethnic tolerance. Ethnic Chinese, which accounted for approximately 3 percent of the population, played a major role in the economy, and increasingly participated in politics. However, some ethnic Chinese noted that, despite recent reforms, public servants still discriminated against them when issuing marriage licenses and in other services. Some activists assert that most cases of discrimination against ethnic Chinese persons go unreported. Some public officials made public statements that government officials of Chinese ethnicity made decisions based on their heritage and not based on national interest. Discussions of corruption on local blogs at times degenerated into racial diatribes.
