It noted that Taiwanese, Saudi Arabian, Hong Kong, Singaporean, South African, and Mexican companies derive more than half of their revenue from foreign markets. "Taiwanese, Mexican, Japanese, Saudi Arabian and S Korean companies are the most exposed to the US, each generating more than 10 per cent of their revenue from the US. Taiwanese companies, in particular, generate 27 per cent of their revenue from the US market, largely because Taiwan is an important part of semiconductor supply chain and serves as major suppliers for Apple," said the report.

Hong Kong, Taiwanese, and South African companies also derive a significant percentage of revenue from developed Europe.
