The White Home has requested South Korea to induce its chipmakers to not fill any market hole in China if Beijing bans Idaho-based Micron from promoting chips, because it tries to rally allies to counter Chinese language financial coercion.
The US made the request as President Yoon Suk-yeol prepares to journey to Washington for a state go to on Monday, based on 4 individuals aware of the talks between the White Home and presidential workplace in Seoul.
China this month launched a nationwide safety assessment into Micron, one of many three dominant gamers within the international Dram reminiscence chip market, with South Korea’s Samsung Electronics and SK Hynix.
It’s unclear if the Our on-line world Administration of China will take punitive motion after its probe. However the stakes are excessive for Micron as mainland China and Hong Kong generated 25 per cent of its $30.8bn in income final yr.
US officers and enterprise executives consider the CAC probe is Beijing’s retaliation towards the powerful actions that President Joe Biden has taken to assist stop China from acquiring or producing superior semiconductors.
The Micron case has emerged as a litmus check of whether or not Beijing is keen to take coercive financial measures towards a serious US firm for the primary time.
The US has requested Seoul to encourage Samsung Electronics and SK Hynix to carry again from boosting gross sales to China if Micron is banned from promoting because of the investigation, based on individuals aware of the scenario.
The White Home’s request comes at a delicate time with Yoon arriving in Washington on Monday. Whereas the US has labored with allies to counter China within the safety space within the Indo-Pacific, that is the primary recognized event that it has requested an ally to enlist its firms to play a job.
The South Korean embassy in Washington and Samsung didn’t reply to requests for remark. SK Hynix mentioned it had not acquired a request from the South Korean authorities. Micron declined to remark.
The White Home didn’t touch upon specifics, however mentioned the Biden and Yoon administrations had made “historic progress” deepening co-operation on nationwide and financial safety points, together with efforts to guard “modern applied sciences”.
“This consists of efforts to co-ordinate investments within the semiconductor sector, safe crucial applied sciences, and handle financial coercion,” mentioned the US Nationwide Safety Council. “We count on the upcoming state go to to even additional strengthen co-operation on all these fronts.”
It’s unclear how Seoul has responded. US and South Korean officers are finalising the go to. They’re discussing many points, together with how the US may give Seoul extra assurance about “prolonged deterrence” — the US nuclear umbrella — as North Korea ratchets up tensions on the peninsula.
The Micron-related request places Yoon in a sophisticated place. He took workplace final yr on a platform broadly thought to be extra hawkish on China than that of his left-leaning predecessor, Moon Jae-in. Illustrating his stance, he provoked an indignant response from Beijing final week by accusing China of making an attempt to alter the established order over Taiwan “by drive”.
However his administration has additionally chafed at US efforts to rally allies behind its financial safety agenda, amid fears that the long-term competitiveness of Samsung and SK Hynix may very well be undermined by US export controls.
Whereas Samsung and SK Hynix won’t welcome efforts to curtail their enterprise in China, the US could have some leverage. When the US unveiled sweeping chip-related export controls on China final October, it gave South Korean firms with chip fabrication services in China waivers to permit them to export from the nation. These waivers have to be renewed later this yr. The commerce division mentioned it had no replace on the scenario.
Reminiscence chip producers are already beneath stress attributable to an trade glut that within the first quarter of this yr triggered a 25 per cent decline within the worth of Dram chips, that are utilized in every part from TVs to telephones.
Final week, Treasury secretary Janet Yellen mentioned Washington was involved about “a latest uptick in coercive actions focusing on US companies”.
One individual aware of the scenario mentioned the request to Seoul displays the truth that the Biden workforce was “motivated to make sure that China is just not going to have the ability to use Micron as a lever to affect or impact US coverage”.
He mentioned the US may assist stymie Chinese language efforts at financial coercion by exhibiting Beijing that it could work with allies and companions to undermine any such transfer towards American or allied firms.
China has used financial coercion towards Taiwan and different nations together with Lithuania and Australia. But it surely has kept away from taking main motion towards the US at the same time as Biden has unveiled powerful chip export controls and imposed sanctions on different Chinese language firms.
One one that just lately met Chinese language officers in Beijing mentioned they had been dropping persistence at what they noticed as US efforts to crack down on Chinese language firms, suggesting that it was contemplating retaliation.
The US request to Seoul underscores how chips are on the coronary heart of a number of the deepest faultlines between Washington and Beijing.
In December, the US put Yangtze Reminiscence Applied sciences Co, a reminiscence chip producer the White Home has known as a Chinese language “nationwide champion”, on its “entity record”. Meaning firms are barred from exporting American know-how to the nascent Micron rival and not using a hard-to-obtain licence.
