North Korea has warned the United States it will seriously consider returning to a state policy aimed at building nuclear weapons if Washington does not end tough economic sanctions against the regime.
For years, the North had pursued a byungjin policy of simultaneously developing its nuclear capabilities alongside the economy.
In April, citing a fresh climate of detente and peace on the peninsula, North Korean leader Kim Jong Un declared the nuclear quest complete and said his country would focus on socialist economic construction.
But a statement issued by the North’s foreign ministry said Pyongyang could revert to its former policy if the US did not change its stance over sanctions.
At a historic summit in Singapore in June, US President Donald Trump and Kim signed a vaguely-worded statement on denuclearisation.
