The statement said:

The chief of the Strategic Center for Asia of the Economic Institute of the Russian Academy of Sciences said the DPRK's line of simultaneously pushing forward economic construction and the building of nuclear force has proven effective.

Despite sanctions and pressure, the DPRK had access to powerful nuclear deterrent and performed innovative successes in the economic construction.

The economy of the DPRK is developing as days go by. This is because the DPRK has put many efforts into economic construction. Sanctions will not help settle the Korean issue. Moreover, forcing the DPRK to surrender won't make sense.
