Hong Kong’s chief executive Leung Chun-ying has accused external forces from various countries of attempting to destabilize the situation in the Asian financial center.

Speaking in an interview with ATV World that aired on Sunday, Chun-ying said: “I shan’t go into details, but this is not entirely a domestic movement.”

He said various people and organizations from abroad have been meddling in Hong Kong’s political affairs, declining to name the particular countries.

“This is not the only time when they do it, and this is not an exception either,” he added.

The Hong Kong leader stressed that the Occupy Central movement is already “out of control even for the people who started it.”

In September, Chinese state media reported that the US secret services were trying export the successful experience of “color revolutions” from Eastern Europe to Hong Kong.

Meanwhile, the leaders of protests have decisively denied reports that foreign forces are behind the events.

The student-led protests, which broke out over three weeks ago, are demanding reforms on how Beijing vets Hong Kong candidates for elections in 2017 as well as the resignation of the current leader.
