The UN chief also said he has been offering his "good offices in relation to the dialogue between the two countries that, until now, had no conditions of success."
Guterres was speaking to reporters at the UN headquarters in New York.
The UN chief was responding to a question on his repeated urging of dialogue between the two South Asian neighbours.
In relation to the human rights situation, the Office of the High Commissioner for Human Rights has produced recently a very detailed report. So, the UN has clearly done its job in that regard, Guterres said to a question by a Pakistan journalist on the situation in Kashmir.
