After that he went back to Washington D.C. to serve in the State Department's Economic Bureau, and on the China Desk.

In 2020, Boucher, along with over 130 other former Republican national security officials, signed a statement that asserted that U.S. President Donald Trump was unfit to serve another term, and "To that end, we are firmly convinced that it is in the best interest of our nation that Vice President Joe Biden be elected as the next President of the United States, and we will vote for him."[4]
