Allen & Overy (A&O) has opened a second mainland China office in the financial centre of Shanghai as the firm gears up for the expected boom in work following China’s entry into the World Trade Organisation (WTO).

The firm, which already has an office in Beijing, is using the abandoned Shanghai office of Dutch firm Loeff Claeys Verbeke as its base. Although Loeff Claeys in Europe is no longer a functioning law firm – after large numbers of its partners in Amsterdam and Belgium joined A&O – the firm still exists on paper.
