South Korean presidential chief of staff Kang Hoon-sik said on Tuesday he would travel to Kazakhstan, Oman, and Saudi Arabia to secure supplies of crude oil and naphtha amid disruptions to shipping through the Strait of Hormuz.

Kang would depart later on Tuesday as President Lee Jae Myung's special envoy to hold talks with governments, energy firms, and ship operators to ensure cargoes reach domestic ports and to support stable supplies of key goods, including medical products, he said.

South Korea urgently needed to diversify its supply lines, as the country relied on the Hormuz route for about 61% of its crude oil and 54% of its naphtha imports, he said at a press briefing at the presidential Blue House.

Oil shipments already arriving in South Korea

Kang said shipments of crude oil and naphtha secured last month from the United Arab Emirates under a 24-million‑barrel supply deal had already started arriving at South Korean ports.

The government was also working with international partners to ensure the safe passage of 26 South Korean-flagged vessels currently waiting inside the Strait of Hormuz, he said.

Kang urged households and businesses to actively take part in energy-saving measures to help the country weather tight supply conditions.
