What happened

During their high-stakes meeting in Beijing this week, Chinese President Xi Jinping reportedly asked US President Donald Trump if the two countries could overcome the “Thucydides trap”.

Why it matters

SINGLE SOURCE

While the general concept of the Thucydides Trap is mentioned in the context of Xi's warning, the specific evidence provided for this claim consists of dictionary definitions of the word 'term' and does not explicitly corroborate Graham Allison's role or the timing. However, the claim is a widely known academic fact; but based strictly on the provided evidence, there is no direct corroboration of Allison's specific involvement.
