The top leader of the Democratic People's Republic of Korea (DPRK) has said the building of DPRK-U.S. relations depends entirely on the United States, the official news agency, Korean Central News Agency (KCNA), reported on Thursday.

Kim Jong Un, general secretary of the Workers' Party of Korea, made the remarks as he delivered a work review report during sessions of the ruling party's Ninth Congress, which took place from February 19 to 25, according to KCNA.

Kim said there is no reason his country cannot get along with the United States if the latter withdraws its hostile policy. He warned that if the United States does not end its confrontational approach, the DPRK would respond, KCNA reported.

"The expansion and strengthening of the U.S.-led aggressive blocs in the Asia-Pacific region and their military activities beyond a tolerance limit are clearly bringing about a grave situation that seriously threatens the security of the Korean Peninsula and the region," Kim noted in his report.
