Outgoing U.S. Ambassador to South Korea Harry Harris on Wednesday praised Foreign Minister Kang Kyung-wha for her contribution to bilateral relations.

In a Twitter post, Harris called Kang a "stalwart" in the alliance and wished her "fair winds and following seas" as she departs office.

He said the foreign minister elevated South Korea's standing in the world and that she will be missed, adding it was an honor to work with her and her team.

Harris will return home Thursday timed with President-elect Joe Biden's inauguration. In the U.S., it is customary for envoys appointed by the previous administration to resign once a new president takes office. 

Rob Rapson, the deputy chief of mission, will serve as charge d'affaires until a new envoy arrives.
