U.S. Sanctions on North Korea

In this article, the recent sanctions that the United States placed on North Korea over the summer are discussed. These sanctions were made to cut off North Korea's funding sources that are used for their nuclear program. North Korea claims that these sanctions may increase their chances of developing more nuclear weapons.
In the article, North Korean spokesman Ri Tong Il is quoted. "The sanctions are a direct expression of intensified hostility. The U.S. should make concrete steps toward engaging in dialogue if it is serious about ridding the Korean peninsula of nuclear weapons."
I find this quote pretty ridiculous. The U.S. is not being hostile by preventing North Korea from building more nuclear weapons as if they don't have enough of them already. I also don't know how someone from North Korea, a threatening country with nuclear weapons that holds innocent people in concentration camps, could call these sanctions "hostile."
Also, the spokesman suggests that the U.S. should take smaller steps in discussing this issue with the DPRK if they want denuclearization. The U.S. has been doing that in the six-party talks that North Korea recently backed out of. If North Korea cooperated a bit more, perhaps the U.S. wouldn't have had to place these sanctions on them. If North Korea wants us to be less hostile, they should probably think about being more negotiable.
The intentions of the U.S. were not harmful in the least bit. According to Hillary Rodham Clinton, the sanctions were placed on the North Korean government and not the citizens, who have "suffered too long due to the misguided and malign priorities of their government." Our country recognizes the horrific issues in North Korea whether it be nuclear programming or the lack of human rights and is trying to resolve these. Clinton also said that the sanctions were partly because of North Korea's fatal warship attack on South Korea, which North Korea still refuses to apologize for.
After reading the article, North Korea certainly sounds more "hostile" than the United States... and hypocritical.
