<P0-S0> on 30 september, zhou enlai warned the united states that china was prepared to intervene in korea if the united states crossed the 38th parallel. <P0-S1> zhou attempted to advise north korean commanders on how to conduct a general withdrawal by using the same tactics which had allowed chinese communist forces to successfully escape chiang kai-shek's encirclement campaigns in the 1930s, but by some accounts north korean commanders did not utilize these tactics effectively. <P0-S2> historian bruce cumings argues, however, the kpa's rapid withdrawal was strategic, with troops melting into the mountains from where they could launch guerrilla raids on the un forces spread out on the coasts. <SEP> <P1-S0> the African Group, with 54 member states the Asia - Pacific Group, with 53 member states the Eastern European Group, with 23 member states the Latin American and Caribbean Group (GRULAC), with 33 member states the Western European and Others Group (WEOG), with 28 member states, plus 1 member state (the United States) as an observer state. <SEP> <P2-S0> By 1 October 1950, the UN Command repelled the KPA northwards past the 38th parallel; the ROK Army crossed after them, into North Korea. <P2-S1> MacArthur made a statement demanding the KPA's unconditional surrender. <P2-S2> Six days later, on 7 October, with UN authorization, the UN Command forces followed the ROK forces northwards. <P2-S3> The X Corps landed at Wonsan (in southeastern North Korea) and Riwon (in northeastern North Korea), already captured by ROK forces. <P2-S4> The Eighth U.S. Army and the ROK Army drove up western Korea and captured Pyongyang city, the North Korean capital, on 19 October 1950. <P2-S5> The 187th Airborne Regimental Combat Team ("Rakkasans") made their first of two combat jumps during the Korean War on 20 October 1950 at Sunchon and Sukchon. <P2-S6> The missions of the 187th were to cut the road north going to China, preventing North Korean leaders from escaping from Pyongyang; and to rescue American prisoners of war. <P2-S7> At month's end, UN forces held 135,000 KPA prisoners of war. <P2-S8> As they neared the Sino-Korean border, the UN forces in the west were divided from those in the east by 50–100 miles of mountainous terrain. <SEP> <P3-S0> the korean war was a conflict between the united states and its united nations allies and the communist powers under influence of the soviet union (also a un member nation) and the people's republic of china (which later also gained un membership). <P3-S1> the principal combatants were north and south korea. <P3-S2> principal allies of south korea included the united states, canada, australia, the united kingdom, although many other nations sent troops under the aegis of the united nations. <P3-S3> allies of north korea included the people's republic of china, which supplied military forces, and the soviet union, which supplied combat advisors and aircraft pilots, as well as arms, for the chinese and north korean troops. <SEP> <P4-S0> Khabarovsk is served by the Khabarovsk Novy Airport with international flights to East Asia, Southeast Asia, European Russia, and Central Asia. <SEP> <P5-S0> Igor Sacharow-Ross (born 1947 in Khabarovsk) is a German-Russian visual artist who works in Cologne and Munich. <P5-S1> He is considered a pioneer in the realm of interdisciplinary art.
