The world's biggest accountancy firms may increase their China staff by more than 20% this year as demand for international accounting expertise soars. More and more state-owned enterprises are going after overseas listings and smaller companies are adopting new accounting standards, the Financial Times reported. That has left the big accounting firms understaffed. PriceWaterhouseCoopers, the biggest of the big four, plans to add more than 2,000 new people – new graduates and experienced staff, to its Hong Kong and China offices. The problem may be finding these people. A lack of qualified accountants in China may leave the big four fighting for the same people.
