Yaoning 'Mike' Sun, the ex-fiancé of Arcadia Mayor Eileen Wang, has been sentenced to 48 months in federal prison for acting as an undisclosed agent for the People's Republic of China.
Sun, a 65-year-old political strategist, admitted guilt in October 2025 for functioning as an unlawful agent of a foreign government.
Prosecutors said Sun deliberately followed the instructions and control of PRC officials from 2022 until January 2024 without informing the US Attorney General, a legal obligation under the Foreign Agents Registration Act (FARA).
Sun leveraged his political expertise to collaborate with US-based associates to promote China's interests within American political frameworks.
He formed a team to assist in the election of a candidate to a local city council in November 2022 and acted as that candidate's campaign adviser while getting orders from PRC officials.
