Mainland China, G7 responses to Taiwan escalation would harm all parties, research finds


Mainland China would squelch hundreds of billions of US dollars in trade and investment from Western countries if ever faced with sanctions over a severe worsening of relations with Taiwan, researchers said in a recent report.

But analysts cautioned that despite that defensive capacity, the mainland’s economy may be too weak to shrug off sanctions of the type placed on Russia, while a Taiwanese business scion called the all-important tech sector on both sides conflict-proof.

If the G7 – the Group of 7, a bloc of seven advanced economies – enacts sanctions against China, Beijing can restrict exports of “critical goods” and the activity of foreign investors, the Atlantic Council think tank said in an April 2 report co-authored with research provider Rhodium Group.

“While still extremely costly in economic terms, these tools are nonetheless likely to be considered in a crisis since the costs of war are far higher,” said the report, titled “Retaliation and Resistance”.

“Just as theories of nuclear deterrence account for the concept of second-strike capabilities, so too must we consider economic retaliatory measures in assessing the deterrence character of sanctions.”

Beijing sees Taiwan as a part of China that will eventually be reunited, by force if necessary. Most countries, including the US, do not recognise Taiwan as an independent state, but Washington opposes any attempt to take the island by force and remains committed to supplying it with weapons.

Cross-strait ties have declined since August 2022, when former US House speaker Nancy Pelosi paid a visit to Taiwan in defiance of Beijing’s warnings. The mainland responded with a week of military drills around the island.

Concerns over further escalation of tensions across the strait, including but not limited to military conflict, have pushed some companies to make arrangements to mitigate possible disruptions to business operations and supply chains.

But for Frank Huang, chairman of Taiwan-based Powerchip Semiconductor Manufacturing Corp, even a hot war could not break investment and supply chain links.

His firm has no contingency plan for a conflict, and plans are in motion to expand investment in a mainland joint venture, Nexchip Semiconductor, the chairman told the Post.

“If you go down to the bottom line of the supply chain of Taiwan, you will find there won’t be a war between the two sides – it’s too big a deal, nothing the military can repress,” he said. “We have to live together.”

But Huang is eyeing India for future expansion, too. The populous, fast-growing South Asian country has its own tech ecosystem and ample educated talent, he said.

‘Bitter fruit’ for foreign supporters of Taiwan independence, Beijing warns

The Atlantic Council evaluated the mainland’s would-be response to G7 sanctions imposed under two scenarios for cross-strait tensions, “moderate” or “higher-escalation”.

G7 members may impose sanctions ahead of any military fight, the report said, and officials in Beijing are already “developing capacities” to become more resilient to Western sanctions after taking note of restrictions brought against Russia over the past two years – even if that resilience would hurt employment at home.

Export restrictions, while costly, would be among the “most impactful economic statecraft tools”, according to the Atlantic Council. Researchers said mainland China would aim to cause “asymmetric pain” through limiting shipments of rare earth materials, clean energy commodities and active pharmaceutical ingredients.

In a “higher-escalation scenario” of G7-wide sanctions, about US$358 billion in G7 exports to the mainland “could be at risk” as a consequence of imposing those measures as well as projected reprisals, the Atlantic Council said.

“On the import side, we estimate that the G7 depends on more than US$477 billion in goods from [mainland] China which could be made the target of export restrictions. Regarding investment, at least US$460 billion in G7 direct investment assets would be at immediate risk from the combined impact of G7 sanctions and retaliatory measures by Beijing,” the report read.

“While export restrictions would be one of [mainland] China’s most impactful economic statecraft tools, it would also be among the costliest options,” the report’s authors said.

Over 100 million jobs in the mainland depend on foreign final demand, with nearly 45 million premised on demand from G7 countries.

In recent years, Beijing has used tariffs, import bans, product boycotts and inspections to “punish firms and countries” for their stances on Taiwan among other sensitive issues, the research paper said, and the authors anticipated more of the same if needed. Audits, fines, permit delays and preferential treatment for non-G7 investors were all included as potential future responses.

“Many multinational corporations would be executing plans to exit the market even before considering retaliatory action,” the Atlantic Council said. “[Mainland] China would have little to gain from holding back on retaliatory actions on a pretence of maintaining ‘investability’.”

The mainland would try to divide the G7, stop any “cohesive” responses outside the G7 and leverage yuan internationalisation to wriggle out of the worst outcomes related to sanctions, the researchers said.

The think tank had posited in June that the G7 would likely consider a range of economic measures to deter or punish the mainland during a Taiwan-related crisis.

But the mainland may be preoccupied with other economic problems to fight back, said Chao Chien-min, dean of social sciences at Chinese Cultural University in Taipei. The world’s No 2 economy is struggling with a property crisis, youth unemployment and curtailed consumption, among other issues.

“Total sanctions, that would create a huge impact on the Chinese economy,” Chao said. The mainland, he added, needs Western markets.

However, that need is reciprocal, and G7 economies would suffer in tandem, said Huang Kwei-bo, professor of diplomacy at National Chengchi University in Taipei.

“The economic interdependence between the two parties has been too complicated to tell whether economic sanctions by the G7 and export reorientation by [mainland] China will work as each party wishes,” he said.
