Over the past decades Singapore's economic growth has helped lift hundreds of millions out of poverty. It has also established the region's leadership on critical global issues, including trade and climate change. This is impressive in itself, but even more so if compared with the fate of Africa.
At the time of decolonization, the level of economic development in most of Asia was comparable with that of Africa. Four decades ago, for example, the per-capita income of South Korea was virtually the same as that of Sudan. Yet today South Korea is one of the richest countries in the world while Sudan is among the poorest. Unfortunately, this comparison holds true for most countries in the two regions.
Is the last sentence correct? Could it be ambiguous in the sense that it can refer to Korea's or Sudan's economic development? Could the sentence in rephrased in a better way?
Thanks in advance.
