The FBI believes that spying by the Chinese communist regime is the greatest threat to the United States, as cases are investigated and arrests have increased at an unprecedented rate.

FBI Director Christopher Wray reported on the nearly 1,000 investigations conducted by his 56 offices involving almost all industrial activities, according to the Washington-based Center for Strategic and International Studies.

Wray called the spying conducted by the Chinese regime “the greatest long-term threat to our nation’s information and intellectual property, and to our economic vitality.”

The FBI arrested 19 people where Chinese people were involved in the first 37 days of this year alone, which represents 80 percent of all arrests last year and shows how the cases have skyrocketed compared to the 15 discovered during the previous five years.

“We believe that no country poses a greater threat than communist China,” said FBI counterintelligence chief John Brown, according to the agency.

“Today, Chinese-related investigations make up a larger percentage of our counterintelligence workload than at any other time in the FBI’s history,” Brown said.

The FBI uncovered an intricate strategy developed by the Chinese regime’s spies, including illegal cyberaccess and the corruption of trusted individuals working in the areas from which they want to steal knowledge.

In addition to the physical theft of technology, the criminals are attempting to stop innovation in the country by using their own intelligence services, state enterprises, seemingly private companies, and many agents including graduate students and researchers.

The director of the National Counterintelligence and Security Center, William Evanina, estimated the cost of trade secret thefts by the Asian regime at $300 billion–600 billion.

Likewise, the vice chairman of the Senate Intelligence Committee, Mark Warner, in a hearing at the Council on Foreign Relations in Washington last year condemned the Chinese regime threatening Chinese students in the United States if they do not engage in spying.

“If your son or daughter does not come back [from the United States] and come back with intellectual property, your family will be put in jeopardy,”  Warner said, referring to the way communist agents use threats against students, according to VOA.

Warner also warned about Confucius Institutes that have been established at universities across the United States under the guise of promoting education in the Chinese language and culture, but which many academic officials are beginning to see as “nothing but agents of Chinese services to spy on Chinese students and hold them accountable.”
