【明報專訊】ON a tour of inspection in Heilongjiang, northeastern China, last week, President Xi Jinping talked about how China, a greater power with a population of nearly 1.4 billion people and a territory of 9.6 million square kilometres, had to be self-sufficient in food, the real economy, and the manufacturing industry. He also mentioned the international situation, saying that as unilateralism and protectionism were on the rise, "we have no choice but to embark on a road of self-reliance, which is not a bad thing". After all, "China has to be on its own."
