Diasporas are not gusanos or worms, as Fidel Castro refers to Cubans abroad. They are a channel through which not only money, but also much tacit knowledge, can flow, and they are a potential source of opportunities for trade, investment, innovation, and professional networks.
一国的侨民，以及它所接收的其他国家的侨民，可以成为其发展的巨大财富。侨民可怜虫和寄生虫（菲德尔·卡斯特罗这样称呼海外古巴人）。他们是一个渠道，资金和隐性知识可以通过这条渠道流动；他们也是贸易、投资、创新和专业网络机会的潜在源泉。
