North Korea has a lot of propaganda overstating the power of the North Korean military during the Korean War. Does the North Korean government acknowledge the fact that without Chinese support they would have lost the war? The war was essentially lost until the Chinese had joined the war.
Not sure if this is more current event or historical question.
Yes, DPRK recognizes the role of China in the Korean War. Their supplying of troops is what makes DPRK say their "friendship is forged in blood" and their relationship is as close as "lips and teeth".
Of course, in official media, DPRK downplays both the roles of China and USSR, but China is more officially recognized due to their commitment of troops, which Stalin did not do. I would say their visibility by actually entering the war does not allow DPRK to completely deny China's role as they have done for the USSR.
However, DPRK does not recognize that they would've lost the war without Chinese troops. There were internal contentions between Kim Il Sung and the combined commander of Chinese-North Korean coalition, Peng Dehuai. By 1951, Korean war was pretty much deadlocked in almost the state the borders are today, essentially becoming trench warfare on the ground and heavy air bombing campaign from the US. Peng Dehuai refuted Kim Il Sung's policy of all out attack and instead preferred gradual advancement plus time to rest and regroup, which Kim thought was the reason for the loss (though declared the war a great victory in official media) of their goal of uniting the peninsula.
“The CPVA needs two months to rest and regroup--not a day less. They even may need three months. Without considerable preparations, not a single division is going to the south. Your underestimation of the enemy is a serous mistake and I will not tolerate it. If you think I am not doing my job, you can fire me, court-marshal me, or even kill me.” Peng Dehuai After Leaning to One Side Zhihua Shen and Danhui Li
In the end, Peng Dehuai won the day. While DPRK appreciates their support, their relations with China is not as close as it appears even back in the 50's before the Sino-Soviet Split.
edit: The CPVA is the Chinese People's Volunteer Army -- which was a kind of thanks from the Chinese for Korean volunteers in the Civil War and anti-Japanese resistance. DPRK sent their volunteers first and gained battle experience which allowed them to fight much more fiercely (with some racial undertones) according to American accounts than the South Koreans who pretty much broke in the first days of fighting.
edit: By racial undertones, I mean pretty overt.
