Going back in history we can see that the earliest communist movements have faced strong opposition from the political front. As the communists come into power they face difficulty fulfilling their promises of creating an equal and just society. The USSR and China both saw initial growth in economic trends but faced a downfall due to a lack of incentives and economic stagnation.

In present times, the main challenge in the implementation of communist principles is that the world is largely capitalistic. The countries which seem to be communist are supposedly facing isolation from the world. Technological advancement and rapid globalization have changed the socio-economic dynamics which made it difficult to deal within the traditional communist model.

Another challenge the communists face is social and political resistance as the people love and value their democracy and personal freedom which are very limited in communist countries. Also, the lack of transparency in the governance of the country can erode the public trust in the government.

Overall, the challenges of implementing communism include economic inefficiencies, international isolation, resistance to political and social control, and adapting to a modern globalized world.
