Question: How many states on the continent where Buddhism spread are recognized by the organization that authorized giving troops the ability to follow the North Korean forces north?

<P0-S0> In Asia, the spread of Buddhism led to large-scale ongoing translation efforts spanning well over a thousand years. <P0-S1> The Tangut Empire was especially efficient in such efforts; exploiting the then newly invented block printing, and with the full support of the government (contemporary sources describe the Emperor and his mother personally contributing to the translation effort, alongside sages of various nationalities), the Tanguts took mere decades to translate volumes that had taken the Chinese centuries to render. <P0-S2> [citation needed] <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> this view is supported by a study of the region where these notions originated. <P2-S1> buddhism arose in greater magadha, which stretched from sravasti, the capital of kosala in the north-west, to rajagrha in the south east. <P2-S2> this land, to the east of aryavarta, the land of the aryas, was recognized as non-vedic. <P2-S3> other vedic texts reveal a dislike of the people of magadha, in all probability because the magadhas at this time were not brahmanised. <P2-S4> [page needed] it was not until the 2nd or 3rd centuries bce that the eastward spread of brahmanism into greater magadha became significant. <P2-S5> ideas that developed in greater magadha prior to this were not subject to vedic influence. <P2-S6> these include rebirth and karmic retribution that appear in a number of movements in greater magadha, including buddhism. <P2-S7> these movements inherited notions of rebirth and karmic retribution from an earlier culture[page needed] <SEP> <P3-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. <P3-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. <P3-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> <P4-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. <P4-S1> MacArthur made a statement demanding the KPA's unconditional surrender. <P4-S2> Six days later, on 7 October, with UN authorization, the UN Command forces followed the ROK forces northwards. <P4-S3> The X Corps landed at Wonsan (in southeastern North Korea) and Riwon (in northeastern North Korea), already captured by ROK forces. <P4-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. <P4-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. <P4-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. <P4-S7> At month's end, UN forces held 135,000 KPA prisoners of war. <P4-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.
