The website of 中国疾病预防控制中心 does not contain the statistics. But the second sentence of the People Daily report clearly stated the source (oral, not publication): "中国疾病预防控制中心性艾中心党委书记韩孟杰在国家卫生计生委在线访谈时表示."

(i) Statistics Overview (for HIV/AIDS). United States Center for Disease Control and Prevention, undated http://www.cdc.gov/hiv/statistics/overview/index.html
("HIV Prevalence Estimate: "Prevalence is the number of people living with HIV infection at a given time, such as at the end of a given year. At the end of 2012, an estimated 1.2 million persons aged 13 and older were living with HIV infection in the United States, including 156,300 (12.8%) persons whose infections had not been diagnosed." Prevalence of Diagnosed and Undiagnosed HIV Infection -- United States, 2008-2012. MMWR Weekly, June 26, 2015)
MMWR = Morbidity and Mortality Weekly Report
(ii) According to Census Bureau, US population was 314.1m in 2012 (318.9m in 2014; both estimates). So the HIV prevalence in US (including the undiagnosed, by dividing 1.2 m by 314.1m) is 0.0038, or 平均每万人中有 38 人感染艾滋病毒.
