In China, the Chinese Dream stirs hopes and sets expectations; internationally, it provokes questions and elicits concerns. Here I look outside China - exploring attitudes, suggesting responses and warning of the dangers of self-fulfilling prophecies.

President Xi Jinping's overarching vision of the Chinese Dream has become a grand driver of China's continuing reform and development. The Chinese Dream differs from the American Dream in that it expresses China's collective aspirations - "the great rejuvenation of the Chinese nation" (in Xi's words) - and it differs from the Chinese Dream in Chinese history by embracing the personal dreams of individual Chinese people for attaining happy, healthy, abundant and productive lives.

That the entire world derives material benefits from the Chinese Dream is apparent in a global economy. Higher standards of living mean greater consumption of goods and services in China, which works to create jobs and prosperity in a multiplier effect worldwide. China's commitment to science enables all peoples to share in China's success, often by making new technologies widely available at low costs.
