In 2009, Hu Jintao convened an ambassadorial conference and signaled that China needed to shift from 'hiding capabilities and biting time' to 'actively accomplishing something,' marking the beginning of the belief that China's moment had arrived.

While China faces severe demographic challenges (population potentially halving by 2100), the strategic implications of these problems are probably 20-25 years away; additionally, the population below age 14 recently increased due to an echo boom of children of Cultural Revolution-era baby boomers.

Global trading system credibility, American alliances and partnerships, dollar credibility as a reserve currency (seen in bond market reactions), and US ability to finance itself are all now in question due to tariff policy; this requires clarity about endgame objectives.

It is possible for China to be slowing economically but also more formidable technologically and strategically, and these technological and strategic advantages may matter more in the relevant timeframes for great power competition.

Xi Jinping invested heavily in military modernization, globalization, power projection, international institutions, and Belt and Road Initiative, but all of these programs began under his predecessor Hu Jintao.

The current US-allied coalition has approximately twice the GDP of China, but cannot realize this advantage without breaking down barriers between allies to build integrated defense, economic, and technology capabilities at scale.

Xi Jinping is commanding, confident, does not rely on talking points in the way past Chinese leaders did, and confidently departs from prepared remarks as needed, showing signs of political confidence.

Sophisticated great power diplomacy necessarily involves both competitive pressure and diplomatic engagement simultaneously; the false choice between 'talking to them' or 'beating them up' misses the reality that effective strategy combines both elements.

The recent narrative shift from 'China rising' (2020-2021) to 'China declining' (2022-2024) was driven by specific events: Russia's military underperformance in Ukraine, ChatGPT demonstrating continued American innovation, China's failure to recover post-COVID, acute demographic problems, debt problems, and youth unemployment.

China's current manufacturing share (2%) is striking given it was only 6% of global manufacturing 25 years ago when the US was 30%, representing a massive structural shift in global economic capacity.

By purchasing power parity metrics (which better capture local prices relevant to strategic capability generation), China's economy passed the United States in 2014, making it larger than is commonly recognized in nominal dollar-based GDP comparisons.

American companies dominate in profit share and market capitalization globally, but some of this reflects the strength of the dollar and the fact that American companies optimize for profit while Chinese companies optimize for market share and long-term competitive positioning.

The recommendations in Campbell and Doshi's essay are 'capacity-centric statecraft' aimed at breaking down barriers between allies to build up defense and economic capacity very quickly, requiring integrated flows of military production (Japan and Korea helping build ships in the US) and advanced weapons technology.

There are two potential paths to achieving allied scale: one focused on persuasion and consent, and another with 'Trumpian characteristics' based on coercion, but both could achieve the same strategic outcome if properly sequenced.

Tariffs alone cannot restore US manufacturing capacity against China—factories won't simply appear overnight. Success requires conscious planning, industrial policy, careful sequencing of tariffs, and allied cooperation.

Biden's manufacturing approach combined industrial policy (subsidies and incentives) with regulatory support and achieved massive increases in manufacturing investment, whereas Trump's approach emphasizes tariffs and deregulation but cuts industrial policy, requiring both components to succeed.

Xi Jinping cannot back down from Trump's challenge politically because of the way Trump has framed it as a direct power play, and Xi views national power as his watchword and namesake, so he will likely maintain his position.

Some critics argue the Campbell-Doshi allied scale vision is too late and the ship has sailed, but the authors believe this approach could succeed in the near future if the Trump administration has the discipline and vision to implement it.

The purge of He Dongming, vice chair of the Central Military Commission, suggests Xi may have been selecting for war-fighting capability (FDR model) rather than just purging for loyalty (Stalin model), which has implications for military preparedness against Taiwan.

There was a brief period during the Biden administration where China and the US maintained military restraint in exchange for political restraint on Taiwan, but this stability did not hold and has given way to escalatory cycles.
