“Analysts and policymakers are used to thinking about China’s military as a global security actor,” says @sheenagreitens.bsky.social‬. But its internal security apparatus also plays a significant role. Sheena, @ibkardon.bsky.social, and Cameron Waltz explain: youtu.be/X0Vtai8xccE?...

Delighted to share a new report that's been over a year in the making, with @carnegieendowment.org 's @ibkardon.bsky.social & Cameron Waltz, on China's internal security outreach under GSI: carnegieendowment.org/research/202...

China’s internal security agencies are using global engagement to legitimize its national security vision via non-military security cooperation. @ibkardon.bsky.social, @sheenagreitens.bsky.social, & Cameron Walz analyze China’s foreign security policy: carnegieendowment.org/research/202...

How should we understand China’s system of party-state capitalism, and what sets it apart from other countries with strong state intervention in the economy? Meg Rithmire discusses on #TheWorldUnpacked with @ibkardon.bsky.social: youtube.com/shorts/Qly5_...

Subsea cables carry 95% of the world’s data but are largely invisible in global policy debates. @ibkardon.bsky.social, Jane Munga, and @sophiabesch.bsky.social discuss the geopolitics, economics, and risks surrounding undersea data infrastructure on #TheWorldUnpacked: www.youtube.com/watch?v=sJIq...

How does capitalism function in China, a party-state that tries to maintain “rule by market” without ceding too much control to private capital? @ibkardon.bsky.social discusses with Meg Rithmire on #TheWorldUnpacked: youtu.be/BMb3S8Jin_A?...

❤️💙♥️

Now available in video: my chat with @ibkardon.bsky.social about my new book. (And definitely the first podcast I’ve done on nukes that ends in a hug!) www.youtube.com/watch?v=XjOp...

“The Life of the Party: Past and Present Constraints on the Future of the Chinese Communist Party" Yvonne Chiu, @ibkardon.bsky.social, & Jason M. Kelly’s co-edited publication contains essays from experts on persistent patterns and new developments in Chinese politics since the CCP’s founding.

Out now: @ibkardon.bsky.social sits down with @nktpnd.bsky.social to explore today’s new nuclear age—and what it will take to manage the growing risks of confrontation and escalation. Listen to #TheWorldUnpacked here: the-world-unpacked.simplecast.com/episodes/why...

On this 6/4, sharing a new piece out at Irregular Warfare Initiative with @ibkardon.bsky.social on "Does China's Growing Security Outreach Matter?" (Spoiler: Yes.) Grateful to @atwellkyle.bsky.social & the entire IWI team for the chance to share our analysis: irregularwarfare.org/articles/doe...

SecDef Hegseth's Shangri-La Dialogue speech repeated conventional wisdom that's already eroded. No longer a functional division of getting security from US, prosperity from China. China's emerged as a global security provider, as @ibkardon.bsky.social and I show in @intsecurity.bsky.social:

President Trump’s desire to “get” Greenland isn’t keeping the U.S. secure. By working with – not against – its allies, Washington can counter Russia and China in the Arctic. @ibkardon.bsky.social‬ and @alexgabuev.bsky.social‬ explain for @foreignpolicy.com: foreignpolicy.com/2025/05/26/t...

Appreciate the extensive quotations and use of my data in this excellent article, which puts the Panama Canal ports in their proper global context. context. We are still waiting for the other shoe to drop in this maritime mega-deal…watch this space.

President Trump’s efforts to take the Panama Canal may now be in limbo thanks to a Chinese antitrust investigation. Carnegie’s @ibkardon.bsky.social explained for @nytimes.com . Read the full article here: buff.ly/FkEMSR2

CK Hutchison is accused of "disregarding national interests and national justice and betraying and selling out all Chinese people" over its sale of Panama Canal ports to US. firm BlackRock in a state media commentary posted by China's Hong Kong and Macao office. www.hmo.gov.cn/sgazx/gayw/2...

Just published this short piece on the big Panama Canal port deal and implications for US-China (maritime) competition, and the middle powers squeezed in between. BLUF: BlackRock acquired a huge port-folio of port terminals, planting US flag in a long-neglected sector. rsis.edu.sg/rsis-publica...

And this more recent piece direct.mit.edu/isec/article...

Fascinating piece from @ibkardon.bsky.social and @sheenagreitens.bsky.social on US-Chinese rivalry www.foreignaffairs.com/united-state...

Thanks to @carnegieendowment.org #CarnegieAsia for posting this copy of my testimony to the USCC last week on China's security cooperation with Russia, NK, & Iran: carnegieendowment.org/posts/2025/0...

Of course, the US has no recognizable claims on the Canal, nor has it been 'reclaimed' - but this is a seismic shift in the global commercial maritime landscape. Hutchison is selling off its Panama holdings - and also another 41 terminals in 22 countries. Big deal!! www.reuters.com/markets/asia...

Excited to share my latest piece with @sheenagreitens.bsky.social, just out with International Security: Quarterly Journal (doi.org/10.1162/isec...). Builds on our prior work in @foreignaffairs.com (www.foreignaffairs.com/united-state...) Paywalled for now, but here's the gist: (1/6)

Delighted to see Dr. Chestnut Greitens’ much anticipated book arrive!

Caught in the act. Taiwan’s coastguard said it caught a Chinese-owned freighter cutting a subsea communications cable off its western coast early on Tuesday. www.ft.com/content/eb4a...

So Adani (which had its DFC funding pulled due to US corruption against its owner) still got a better deal at Colombo than China Merchants? Go figure… www.maritimegateway.com/slpas-collab...

@intsecurity.bsky.social @belfercenter.bsky.social @mitpress.bsky.social

A growing number of countries are receiving security assistance from both Beijing and Washington, write Sheena Chestnut Greitens and Isaac Kardon. How should U.S. policymakers navigate these patterns of overlapping cooperation?

Delighted to have a new article out with @ibkardon.bsky.social in International Security. China is emerging as a global security provider, including to countries that get security assistance from the US. 1/3

Grateful for the chance to testify in the House this week about "China's strategic port investments in the Western Hemisphere"...including extensive analysis of the Panama Canal, ZPMC cranes, and the unwisdom of PLA power projection in this hemisphere. homeland.house.gov/hearing/exam...

Sharing my latest @CarnegieEndow piece, with @milomcbride evaluating China's critical mineral export controls as a potent upstream countermeasure against US chip/AI controls. BLUF: China's mineral weapon can hurt global tech industry, but it can't last long. carnegieendowment.org/research/202...

The latest trend in ship design: broken ⚓️ , for a rugged look 🎉

Read the latest by our #PIPFellows @ibkardon.bsky.social and @sheenagreitens.bsky.social on the evolving U.S.-China-Vietnam triangle:

Today we see strategic “non-monogamy,” where countries like Vietnam are working with US on external security and meanwhile cooperating with PRC internal security (policing, surveillance, suppressing opposition). Our piece unpacks this emerging trend in global security alignment in Asia & beyond.

New piece with @sheenagreitens.bsky.social in @foreignpolicy.com on Vietnam and US-China security competition. We argue that this rivalry doesn’t require countries to choose the US or China as sole security partner. That type of bipolarity is Cold War 1.0. (1/2) foreignpolicy.com/2025/01/13/v...

Ratifying UNCLOS has long been a no-brainer. From a national security, economic, or diplomatic standpoint, the USA has almost nothing to lose and a great deal to gain by joining this treaty (one that we already accept as custom). This review of my book (and two others) supports that sound argument.

Tune in/show up tomorrow 9am for our conversation, covering evolving Russian, Chinese, and American strategic goals in an increasingly precarious Mideast. Especially keen to cover whether and how PRC will have to play a bigger role, given Russia's compromised position in Syria & changing US admin.

The Middle East and the Horn of Africa have reemerged as the locus of major security interests for China, Russia, and the United States. 🗓️ Join Carnegie on Dec. 18 @ 9 AM for an expert panel discussion on great power competition in the region & its broader implications: https://buff.ly/3VtLPFS

Not a surprise that the two South Korean officials most conscious of the global reaction would oppose imposition of martial law. Wrote a bit on that (as-yet underemphasized, I think) aspect of the crisis here: carnegieendowment.org/emissary/202...
