Answer:
In 1950, there was an international anti-slavery that slowed down (due to the ongoing War), but since all forms of slavery were still evolving, there was little attention for both.
Explanation:
During the Cold War, there was an international anti-slavery "campaign" that had slowed down. The Soviet Block (at this time) argued that slavery can only exist in in societies of Capitalists, but the Western Block (at the time) debated that all who followed communism are slaves. New, Old, and traditional forms of slavery received little to no attention back then.
Some more information is that in the 1950s (specifically 1954), it was reported China passed the State Regulation on Reform through Labor. This regulation allowed prisoners to be used for forced labor in their prisons camps located in Laogai. As well as in 1956, The Supplementary Convention on Slavery Abolition regulates practice of serfdom, debt bondage, the sale of wives, and servitude.
Again, not much attention was pointed to Slavery, and the attention that was not BIG.
