Candidate passages:
In the aftermath of the war, under Lê Duẩn's administration, the government embarked on a mass campaign of collectivization of farms and factories.
This caused economic chaos and resulted in triple-digit inflation, while national reconstruction efforts progressed slowly.
At least one million South Vietnamese were sent to reeducation camps, with an estimated 165,000 prisoners dying.
Between 100,000 and 200,000 South Vietnamese were executed in extrajudicial killings; another 50,000 died performing hard labor in "New Economic Zones".
In the late 1970s and early 1980s, millions of people fled the country in crudely built boats, creating an international humanitarian crisis; hundreds of thousands died at sea.
In 1978, the Vietnamese military invaded Cambodia to remove from power the Khmer Rouge, who had been attacking Vietnamese border villages.
Vietnam was victorious, installing a government in Cambodia which ruled until 1989.
This action worsened relations with the Chinese, who launched a brief incursion into northern Vietnam in 1979.
This conflict caused Vietnam to rely even more heavily on Soviet economic and military aid.
At the Sixth National Congress of the Communist Party of Vietnam in December 1986, reformist politicians replaced the "old guard" government with new leadership.
The reformers were led by 71-year-old Nguyen Van Linh, who became the party's new general secretary.
Linh and the reformers implemented a series of free-market reforms – known as "" ("Renovation") – which carefully managed the transition from a planned economy to a "socialist-oriented market economy".
Though the authority of the state remained unchallenged under "Đổi Mới", the government encouraged private ownership of farms and factories, economic deregulation and foreign investment, while maintaining control over strategic industries.
The Vietnamese economy subsequently achieved strong growth in agricultural and industrial production, construction, exports and foreign investment.
However, these reforms have also caused a rise in income inequality and gender disparities.
Collectivization in the Soviet Union was a policy, pursued between 1928 and 1933, to consolidate individual land and labour into collective farms (, "kolkhoz", plural "kolkhozy").
The Soviet leaders were confident that the replacement of individual peasant farms by kolkhozy would immediately increase food supplies for the urban population, the supply of raw materials for processing industry, and agricultural exports generally.
Collectivization was thus regarded as the solution to the crisis in agricultural distribution (mainly in grain deliveries) that had developed since 1927 and was becoming more acute as the Soviet Union pressed ahead with its ambitious industrialization program.
As the peasantry, with the exception of the poorest part, resisted the collectivization policy, the Soviet government resorted to harsh measures to force the farmers to collectivize.
In his conversation with Winston Churchill Stalin gave his estimate of the number of "kulaks" who were repressed for resisting collectivization as 10 million, including those forcibly deported. 
After World War II, Poland became a communist country, a satellite of the Soviet Union.
Since collective farming is a key component of communist notion of agriculture, in June 1948, the Polish United Workers' Party, spurred by the announcement of the Komintern, decided to begin the process.
From the very beginning, compulsory collectivization faced strong resistance of Polish farmers, who did not want to give up their land.
Despite using different methods of persuasion, the progress was slow.
By 1951, only 1% of arable land was collectivized, with some 23 000 farmers working there.
Altogether, in that year there were some 2200 collective farms.
Most of them were located in western and northern Poland, in the Recovered Territories, where population consisted of people resettled from former eastern borderlands of Poland.
After the Polish October, Władysław Gomułka officially declared that private farms were part of the so-called "Polish road to Socialism" and the government gradually changed its stance.
In the late 1950s, number of collective farms fell to 1 800, and Poland was the only country of the Soviet Bloc which tolerated private ownership of the arable land.
In 1958, Moscow ordered the resumption of collectivization, but unlike her neighbors, Poland refused.
By 1960, collectivization in Poland was ended, never to be resumed, and Engels' opinion that peasants would spontaneously create collective forms of agricultural production because of the threat of the big landed estates was not confirmed in Poland.
Preservation of individual agriculture was a key factor in future events.
Nevertheless, forced collectivization of farmland had disastrous consequences, as Poland, traditionally a grain exporter, had to import food, including grain, to prevent famine. 
Collectivization in the Ukrainian Soviet Socialist Republic was part of the policy of Collectivization in the USSR and dekulakization that was pursued between 1928 and 1933 with the purpose to consolidate individual land and labour into collective farms called kolkhoz and to eliminate enemies of the working class.
The idea of collective farms was seen by peasants as a revival of serfdom.
In Soviet Ukraine this policy had a dramatic effect on the Ukrainian ethnic population and its culture as 86% of the population lived in rural settings.
The forceful introduction of the policy of collectivization was one of the main causes of the Holodomor.
In Ukraine collectivization had specific goals and outcomes.
According to a Soviet official explaining the goals: "A ruthless struggle is going on between the peasantry and our regime.
It's a struggle to the death.
This year was a test of our strength and their endurance.
It took a famine to show them who is master here.
It has cost millions of lives, but the collective farm system is here to stay.
We have won the war.
"The Soviet policies related to collectivisation have to be understood in the larger context of the social "revolution from above" that took place in the Soviet Union at the time.
The formation of Collective farms were based on the large village farms in collective ownership of village inhabitants.
Estimated yields were expected to increase by 150%.
The ultimate goal of collectivization was to resolve "grain problems" of late 1920s.
In the early 1920s only 3% of the peasantry of the USSR were collectivised.
Within the first five-year plan 20% of peasant households were to be collectivised, although in Ukraine the number was set at 30%. 
The price of collectivization was so high that the March 2, 1930, issue of "Pravda" contained Stalin's article "Dizzy with success", in which he called for a temporary halt to the process:"It is a fact that by February 20 of this year 50 percent of the peasant farms throughout the U.S.S.R. had been collectivized.
That means that by February 20, 1930, we had "overfulfilled" the five-year plan of collectivization by more than 100 per cent... some of our comrades have become dizzy with success and for the moment have lost clearness of mind and sobriety of vision."
After the publication of the article, the pressure for collectivization temporarily abated and peasants started leaving collective farms.
According to Martin Kitchen, the number of members of collective farms dropped by 50% in 1930.
But soon collectivization was intensified again, and by 1936, about 90% of Soviet agriculture was collectivized.
