Taiwan boasts a strong legal market, thanks in part to its leading role in semi-conductor and other high-tech manufacturing. The legal market in Taipei – and, indeed, elsewhere around Taiwan – is robust and competitive, giving it outsize strength for a jurisdiction with a working age population of just 16.55 million people.


Taiwan’s strength in technology extends to pharmaceuticals, these days. In August 2021, President Tsai Ing-wen received her first dose of the island’s do-mestically developed coronavirus vaccine. The vaccine, developed by Medigen Vaccine Biologics Corp., was giving emergency approval by regulators in July.
