The working-level talks between U.S. and North Korean envoys in Stockholm, Sweden, were broken off on Saturday.
In response, Stockholm proposed an alternative meeting in two weeks' time.
Now, Reuters reports North Korea refused the offer on Sunday.
North Korea warned Washington it would wait only until the end of the year for the United States to change course.
We have no intention to hold such sickening negotiations as ... happened this time in Sweden before the U.S. takes a substantial step to make complete and irreversible withdrawal of the hostile policy toward the DPRK.
