"Pompeo has gone so far in his language and it made the opening of the expected DPRK-U.S. working-level negotiations more difficult ... Our expectations of dialogue with the US are gradually disappearing and we are being pushed to re-examine all the measures we have taken so far," Choe said, as cited by North Korea's state-run KCNA news agency.
On Tuesday, Pompeo said Washington could not ignore North Korea's "rogue behavior" and listed the country among several others as a challenge that Washington faced.
North Korea's leader, Kim Jong Un, has been engaged in dialogue with US President Donald Trump to denuclearize the Korean Peninsula for over a year. However, the talks reached a deadlock in February when a summit between the two leaders in Vietnam ended abruptly without any agreement.
In late June, Kim and Trump met again to agree on resuming the dialogue and holding working-level consultations. However, the tensions around North Korea have still been mounting over the past months amid weapons tests by Pyongyang and US-South Korean military drills, which took place earlier in August and were met with criticism from North Korea.
