envoy mark lippert said in a speech on wednesday that if north korea improves its human rights record and takes steps to end its nuclear program , it will be rewarded with prosperity and better ties with the outside world .
the north 's committee for the peaceful reunification of korea said lippert 's remarks were proof that washington was intent on hostility .
lippert needs to drop the bad habit of rashly engaging in scheming chatter distorting the truth and instigating war by taking issue with us .
