Four U.S. congressmen have admitted they don't know well what is happening in Hong Kong, Regina Ip Lau Suk-Yee, Legislative Council member of Hong Kong Special Administrative Region (HKSAR), said in a recent exclusive interview with China Media Group.

"Facing reports on the Hong Kong police in the U.S. media, I've told the four congressmen that the rioters have taken part in very violent acts," Ip said when she attended a meeting with the American politicians in the U.S. state of Montana, adding that "the congressmen understand and say they respect the police."

"There have been many cases in the U.S. where police shot people dead and been found as not guilty. U.S. politicians totally understand the restraint of Hong Kong police. And, they know how U.S. officials and the government protect police officers," she said.

She acknowledged that there are social problems in Hong Kong, including high rent and housing prices. But, she said the demands need to be expressed in a lawful and rational way.

"The violence has undermined the rule of law and the majority of Hong Kong residents cannot tolerate this."

Many people are not familiar with China's "One country, Two systems" principle and it needs to be better explained, she noted.

"Maybe in the past 22 years, we talked too much about the 'Two systems,' but didn't elaborate enough on the 'One country,' which is fundamentally important. We need to emphasize the 'One country,' and explain it in a way that is more understandable to the young people," said the lawmaker.
