The U.S. and the Republic of Korea have enjoyed a longstanding partnership in energy, ranging from decades-long civil nuclear cooperation to more recent collaboration on climate change and clean energy technology R&D. Under the Trump administration, opportunities exist for this partnership to expand and evolve in key areas, including oil and gas exports, clean coal technology R&D, and nuclear energy. Although considerable uncertainty remains--Trump has yet to confirm his appointments to energy-related Cabinet positions, such as the Energy and Interior Secretary posts[i]--Trump's campaign stances point to a number of themes that may define the U.S.-Korea energy relationship under his term.
