SEOUL (Reuters) - President Moon Jae-in said on Monday South Korea will ensure there is no gap in the alliance with the United States and the process of building peace on the Korean peninsula, as he congratulated Joe Biden on his U.S. presidential election win.South Korea found outgoing U.S. President Donald Trump a willing partner in efforts to meet with North Korea’s Kim Jong Un. However, the relationship was strained by disagreements over exactly how to engage with Pyongyang, trade and Trump’s demand that Seoul pay billions of dollars more to support the U.S. troop presence on the peninsula. “We will gather forces as an alliance on the shared values of democracy, peace, human rights, international solidarity and multilateral cooperation,” Moon told his top aides, the presidential Blue House said in a statement regarding the incoming Biden administration. The South Korean government will work to promote economic relations through bilateral trade and policies and cooperate towards carbon neutrality and tackle climate change, said Moon.
