The US judicial authorities have charged an American citizen and 4 Chinese intelligence officers with spying on prominent opponents of the Chinese regime, human rights leaders and democracy activists residing in the United States.

A statement from the New York Public Prosecution said that the five conspired to silence Chinese dissidents, pro-democracy activists and prominent human rights activists.

The indictment alleges that Wang Shujun of Queens, New York, used his position within the communities of overseas Chinese, dissidents and dissidents to gather information about their activities for China's Ministry of State Security.

The 73-year-old New York-based American Shojun Wang of Chinese descent was arrested on March 16 on suspicion of being an agent of the Chinese government, and he will appear in court at a later date, while the four accused Chinese officers are still on the run, according to the Ministry of Justice.

"The alleged accusations made by the United States are pure lies," the Chinese embassy in Washington said in a written statement sent to Reuters.

"We urge the US side to conduct a fair and lawful investigation, properly handle relevant cases, and protect the legal rights of relevant Chinese citizens," she added.

The indictment added that Wang had provided information to the Chinese Ministry of State Security since at least 2011, noting that its officials directed him to target pro-democracy activists from Hong Kong, defenders of Taiwan independence, Uyghur issues and Tibetan activists.
