Which is the largest developing country in the world?

China is indeed the largest Chinese developer.

Because "largest" refers to national strength. National strength refers to the size of the population, area, economy, politics, military, international influence, and other aspects combined. It's not just the size of the land area.

China's economic development over the years has made remarkable achievements, China's population is large, its international influence is growing, and its GDP has surpassed that of Japan to rank second in the world, after the United States. All these achievements are incomparable to those of other developing countries. That is why China is the largest developing country. Just as the United States is the largest developed country, no one has ever said that Canada is the largest developed country. Within the developed countries, Japan is second and Germany is third, also talking about population and economic strength, no one ever says Canada or Australia.

So China is the largest developing country
