California campaign adviser gets 4 years for acting as Chinese agent

(Oldglorychronicle.com) – A California political operative who helped elect a city council member while secretly working as an unregistered agent for Communist China has been sentenced to four years in federal prison, exposing how foreign adversaries are infiltrating American democracy at the grassroots level.

Sun ran pro-China propaganda website and conducted real-time surveillance of Taiwan’s president during her California visit

Foreign Agent Embedded in Local Politics

Yaoning “Mike” Sun received his sentence from U.S. District Judge R. Gary Klausner on February 10, 2026, following his October 2025 guilty plea to acting as an illegal agent of a foreign government. The Chino Hills resident worked under direction of high-level Chinese intelligence officials while serving as campaign advisor to a candidate who won election to a Southern California city council seat in November 2022. Sun’s dual role as trusted political consultant and covert operative gave the People’s Republic of China direct influence over an American elected official.

Propaganda Operations Target Community

Beginning in 2020, Sun and the unidentified council member operated a news website purportedly serving the local Chinese American community. Federal prosecutors established that Sun posted pro-China propaganda content under specific directives from Chinese government officials. This sophisticated influence operation provided cover for Sun’s intelligence activities while shaping political opinions within one of the largest Chinese American populations in the United States. The San Gabriel Valley operation demonstrates how foreign adversaries exploit immigrant communities to advance their interests on American soil.

Intelligence Gathering on U.S. Soil

Sun’s activities escalated beyond propaganda in April 2023 when he conducted real-time surveillance of Taiwan President Tsai Ing-Wen during her Southern California visit. He reported her movements directly to Chinese consular officials in Los Angeles and photographed protesters, acting as Beijing’s eyes and ears during a foreign leader’s visit to American territory. Sun continued communicating with consulate officials regarding Taiwan-related activities through 2024. In February 2023, he drafted reports to Chinese officials requesting additional funding and assignments, documenting his ongoing operational relationship with the Communist regime.

FBI Sounds Alarm on Electoral Infiltration

FBI Assistant Director Roman Rozhavsky issued a stark warning about the case’s implications: “When Americans vote for elected officials, they expect them to represent the interests of their constituents – not those of a foreign adversary like the Chinese government.” Federal prosecutors emphasized Sun’s “pivotal role in the PRC’s efforts to influence U.S. politicians in their favor at all levels of government,” recommending 60 months imprisonment. The judge’s 48-month sentence split the difference between prosecution recommendations and defense requests for time served, reflecting the serious nature of undermining democratic processes.

Unanswered Questions Remain

Federal authorities continue monitoring for similar foreign influence operations targeting local and midterm elections, but critical questions remain unresolved. The identity of “Individual 1” – the elected city council member who benefited from Chinese government support – has not been publicly disclosed, despite that official remaining in office and potentially vulnerable to foreign influence or coercion. Sun worked under direction of John Chen, a high-level Chinese intelligence operative who met personally with President Xi Jinping and was sentenced to 20 months in November 2024. This case exposes gaps in campaign finance and political operative vetting procedures that foreign adversaries exploit to infiltrate American government at the local level, where oversight is weakest.
