Which policy change was partly responsible for economic growth in china starting in the 1970s

Explanation:

Cuando Mao Zedong llegó al poder en 1949, China estaba sumida en la pobreza y devastada por la guerra.

Hoy, cuando se cumplen 70 años del triunfo de los comunistas, el país es radicalmente diferente: es una potencia mundial de primer orden y aspira a convertirse en la primera economía del globo.

Pero su "milagro económico", único en la historia, no se debió al "Gran Timonel", sino a una campaña impulsada por otro líder comunista, Deng Xiaoping.

Se llamó "Reforma y apertura" y logró sacar a 740 millones de personas de la pobreza, según cifras oficiales

Bajo la idea de un "socialismo con características chinas", Deng rompió con lo establecido e impulsó una serie de reformas económicas, centradas en la agricultura, la liberalización del sector privado, la modernización de la industria y la apertura de China al comercio exterior.

relations between the soviet union and the united states were driven by a complex interplay of ideological, political, and economic factors, which led to shifts between cautious cooperation and often bitter superpower rivalry over the years. the distinct differences in the political systems of the two countries often prevented them from reaching a mutual understanding on key policy issues and even, as in the case of the cuban missile crisis, brought them to the brink of war.

the united states government was initially hostile to the soviet leaders for taking russia out of world war i and was opposed to a state ideologically based on communism. although the united states embarked on a famine relief program in the soviet union in the early 1920s and american businessmen established commercial ties there during the period of the new economic policy (1921–29), the two countries did not establish diplomatic relations until 1933. by that time, the totalitarian nature of joseph stalin's regime presented an insurmountable obstacle to friendly relations with the west. although world war ii brought the two countries into alliance, based on the common aim of defeating nazi germany, the soviet union's aggressive, antidemocratic policy toward eastern europe had created tensions even before the war ended.

sometimes, borders fall along natural boundaries like rivers or mountain ranges. for example, the boundary between france and spain follows the crest of the pyrenees mountains. for part of its length, the boundary between the united states and mexico follows a river called the rio grande. the borders of four countries divide africa’s lake chad: niger, chad, cameroon, and nigeria.
