[News] U.S. Urges South Korea to Tighten Chip Export Controls to China

In recent years, the U.S., Japan and the Netherlands, have increasingly expanding restrictions on China in semiconductor technology. South Korea, on the other hand, has been cautiously responding to U.S. demands due to its significant dependence on the Chinese market.

Yet, according to a report by South Korean media outlet The Korea Herald, the U.S. is increasing pressure on South Korea to comply with its export controls to China.

At the Korea-U.S. Economic Security Conference 2024 held in Washington, D.C. on September 10th, U.S. Commerce Department Undersecretary Alan Estevez called on South Korea’s two leading HBM manufacturers, Samsung and SK hynix, to align with U.S. export controls on China. He urged that their production capacity be reserved for supplying advanced chips to allied nations, rather than competitors such as China.

Estevez emphasized his appreciation for South Korea’s long-standing cooperation with the U.S., but pointed out that since AI can be used for military purposes, it is crucial to prevent China from acquiring advanced chips to train AI models.

South Korea’s Trade Minister Cheong In-kyo responded that while they will discuss the matter with the U.S., export controls have a significant impact on South Korea’s businesses and economy.

Some industry sources cited by The Korea Herald have further pointed out that the direct export volume of chips from Samsung and SK hynix to China is not significant, so the actual impact may be limited.

However, per a previous Reuters report cited sources, it’s indicated that about 30% of Samsung’s HBM chip sales in the first half of this year were to China.

The Korea Institute for Industrial Economics and Trade noted that, unlike Japan and the Netherlands, South Korea cannot fully align with U.S. export control measures due to its significant reliance on exports to China.

Per the Chosun Daily citing data from South Korea’s Ministry of Trade, Industry, and Energy and the Korea International Trade Association, it’s shown that in July of this year, South Korea’s exports to China increased by 14.9% year-on-year to USD 11.4 billion, the highest since October 2022. Notably, memory exports surged 89% year-on-year to USD 6.8 billion.

Semiconductor exports saw particularly strong growth, with chip exports rising 49% year-on-year. In June this year, Korea’s memory exports also amounted to USD 8.8 billion, accounting for 65.8% of total semiconductor exports, which reportedly represents the highest proportion in two years since December 2021.

These figures reflect South Korea’s robust performance in the chip sector and the strong demand from the Chinese market for Korean semiconductors and other ICT products.

Meanwhile, due to the U.S.’s strict restrictions on chip manufacturing technology, China is striving for breakthroughs in the HBM field.

The HBM market is currently dominated by South Korea’s SK hynix, Samsung Electronics, and the U.S.’s Micron, all of which are producing the latest standard HBM3 chips.

However, a report from Tom’s Hardware, citing industry sources, has indicated that Chinese companies, including CXMT, have made progress in developing HBM and are in the early stages of production. Huawei is also collaborating with other Chinese companies, with plans to produce HBM2 chips by 2026.
