South Korea has ratified a controversial trade treaty with the US effectively opening the Asian country’s legal market to foreign law firms, most of which had effectively been barred from practising there, writes The Asian Laywer.

Following Tuesday’s (22 November) ratification of the Korea-US free trade agreement (FTA) – at a parliamentary session marred by protest including a tear gas canister set off by an opposition politician – US firms will be able to set up Korea offices from 1 January 2012. The US Congress approved the treaty last month.
