According to the Washington Post, presidential advisers fear that the DPRK leader "decided to make relatively modest promises" that he "could quickly take back." According to them, Kim Jong-un wants to "create the illusion that he is prudent" and is ready to compromise.
Because of this, Washington will continue to find it harder to abandon the demands of Pyongyang, officials say.
Some of them view UN's promises as an attempt to force the White House to “soften economic sanctions” against the DPRK.
Recall, on Saturday, Pyongyang proclaimed a “new strategic course”, refusing further nuclear and missile tests in order to “focus exclusively on the development of the country's economy.”
This decision was proclaimed in a resolution of the plenum of the Central Committee of the Korean Workers' Party (TPC). Pyongyang also announced the closure of a nuclear test site in the north of the country. Thus, North Korea "joins the international effort to comprehensively end nuclear testing."
The new political course was adopted on the eve of the summit of the DPRK and South Korea, scheduled for 27 in April, as well as the planned meeting of Kim Jong Un with Donald Trump.
