Letters | US tech sanctions on China are a failure to learn from history
- Readers discuss past and present US embargoes and Cathay Pacific workers’ industrial action

I was recently given an old copy of Life International, dated December 7, 1959, featuring what was a new series on the great cities of the world. Han Suyin wrote about Hong Kong, which had to grapple with a stream of refugees from China and embargoes. Many said Hong Kong was doomed. Here is a short excerpt:
“The US placed an embargo on Hong Kong, and it worked both ways: it prohibited Hong Kong from sending goods to China, but it also prohibited Hong Kong from accepting goods from China or North Korea for re-export to the US. That was when the refugees stepped in. ‘Instead of buying these goods from China,’ they said, ‘we shall set up factories and make these things right here in Hong Kong.’ Factories were built.”
