N Korea warns US-S Korea drills will affect nuclear talks

North Korea on Tuesday said looming US-South Korea military drills could impact the proposed resumption of nuclear talks between Pyongyang and Washington, and hinted that it could reconsider its moratorium on nuclear testing.

It was the first statement from Pyongyang on the talks since US President Donald Trump and North Korean leader Kim Jong Un agreed to their resumption at an impromptu meeting in the Demilitarized Zone in June, following months of deadlock between the two sides.

The joint drills have been held for years but were scaled down to facilitate dialogue with the North after Trump's historic first summit with Kim in Singapore last year.

"If the military exercise really goes ahead, it would affect the DPRK-US working-level talks," an unnamed foreign ministry spokesperson said in comments carried by state news agency KCNA, using the official acronym for North Korea.

The official described next month's drills as "clearly a breach" of a joint statement signed by the leaders in Singapore and hinted that Pyongyang may resume weapons tests in response.

Pyongyang's moratorium on nuclear and long-range missile tests was a commitment aimed at improving bilateral relations and "not a legal document inscribed on a paper", the official said.

"With the US unilaterally reneging on its commitments, we are gradually losing our justifications to follow through on the commitments we made with the US as well."
