It says it right in what you posted.

"with intent to influence the measures or conduct of any foreign government or of any officer or agent thereof, in relation to any disputes or controversies with the United States, or to defeat the measures of the United States, shall be fined under this title or imprisoned not more than three years, or both."

So in your enlightened opinion, what dispute or controversies are we currently involved with Ukraine? For example, when John Kerry had talks with Iran that was a violation because we have disputes with them.
