With a mounting pile of pending issues to resolve with the United States—ranging from the progress of US investments to tariff measures—Minister of Trade, Industry and Energy Kim Jeong-kwan departed for the US unexpectedly this morning (August 16).

This marks Minister Kim's visit to the US in about three weeks, following his attendance at the opening ceremony of the Korea-US Shipbuilding Cooperation Center last month, and is reportedly an urgently arranged schedule to discuss trade issues.

During his local stay, Minister Kim is expected to continue discussions on pushing forward US investment projects and addressing US tariff measures related to overproduction.

South Korea and the US agreed last year to lower the US reciprocal tariff from 25% to 15%, on the condition of a $350 billion investment in the US.

The Ministry of Trade, Industry and Energy has selected a combined-cycle gas turbine power plant construction project as the first US investment project and has been coordinating with the US side.

Although the government planned to select the first project within the year, the US has repeatedly urged the South Korean government through diplomatic channels to swiftly implement the investment.

On August 14, US Ambassador to South Korea Michelle Steel met with Minister Kim first among South Korean cabinet ministers, excluding the Minister of Foreign Affairs, leading to interpretations that priority is being placed on US investment.

Amid US investment pressure, the government also needs to respond to tariff measures.

The US is expected to announce the results of its investigation into overproduction based on Section 301 of the US Trade Act by the end of this month.

With the US having previously imposed a 12.5% tariff related to forced labor on South Korea, concerns remain that if additional tariffs are imposed depending on the overproduction investigation results, it could exceed the 15% cap set in last year's South Korea-US trade agreement.

The government maintains its stance that a consensus exists between South Korea and US trade authorities not to exceed the 15% upper limit, but the progress of US investments could act as a variable.

US President Donald Trump also abruptly pressured for investment implementation last January by posting on his social media network that he would raise tariffs on South Korean products such as automobiles from 15% to 25%.

Minister Kim's burden has grown heavier due to the vacancy left by former Trade Minister Yeo Han-koo, who had played a central role in South Korea-US tariff negotiations and other matters.

President Lee Jae-myung dismissed former Minister Yeo yesterday.

While the government did not disclose specific reasons, it is reportedly an issue unrelated to the South Korea-US tariff negotiations.

With a vacancy created before a successor is appointed, continuity in South Korea-US trade negotiations is expected to face disruptions for the time being.

The Ministry of Trade, Industry and Energy is activating an emergency operation system led by Assistant Minister for Trade Park Jung-sung.

Minister Kim is also expected to explain former Minister Yeo's vacancy during his visit to the US.
