President Donald Trump's second meeting with North Korean leader Kim Jong Un will be more intensive than the inaugural round last year in Singapore, administration officials said on Thursday.
The Singapore summit had drawn a vague promise from Kim to denuclearize the Korean Peninsula, but the agreement they signed had no concrete deadlines or steps laid out. A common definition of "denuclearization" doesn't even exist yet, officials say.
Denuclearization talks have stalled, and in December, state-run Korean Central News Agency (KCNA) published a commentary saying North Korea will not relinquish its nuclear weapons until the US eliminates its own "nuclear threat."
Since the Singapore summit, Trump has repeatedly claimed that success is evident because Pyongyang has stopped testing ballistic missiles or nuclear bombs (for now). But US intelligence agencies say publicly there's no sign Kim is preparing to relinquish his arsenal.
Privately, Trump's advisers believe more concrete progress -- beyond a series of friendly handshakes -- will be necessary during this summit to prove the diplomacy is working. Trump, meanwhile, has touted his warm relationship with Kim as progress in itself, and brandished the glowing letters he's received from Kim in meetings with hostile lawmakers.
