Accusing the U.S. of sheltering a visually-challenged activist in its embassy here using “abnormal means”, China on Monday asked America not to repeat such an incident in the overall interest of bilateral ties.

China termed the incident as “interference” in the internal affairs of the country.

40-year-old Chen Guangcheng fled house arrest last month for the U.S. embassy, where he spent six days. He was later shifted to a hospital after Beijing said that he could move to a “safe” location.

But Chinese Foreign Ministry spokesman Hong Lei declined to answer questions over when Mr. Chen and his family would be given passports to travel to U.S.

American officials say they expect the process to be over by this week.
