(Corrects first and sixth paragraphs in April 19 story to show private firms will still require government approval but not parliamentary approval.)
* Private firms no longer need parliamentary approval
* Curbs on foreign SOEs to be tightened
* Law blamed for deterring foreign investment in Mongolia
ULAN BATOR, April 19 (Reuters) - Private firms looking to invest in Mongolia will no longer have to seek the approval of the country's parliament after lawmakers amended a controversial foreign investment law on Friday.
Mongolia's Strategic Entities Foreign Investment Law (SEFIL), passed in May 2012, was designed to restrict foreign investment in firms in sectors like mining to just 49 percent, and came amid concerns about the growing role played by overseas capital in the country's mining-led economic boom.
But the law, passed shortly after China's Chalco made a bid to buy a majority stake in the Mongolia-focused coal miner SouthGobi Resources, was heavily criticised by investors worried about the growth of Mongolian "resource nationalism."
Partly as a result of the law, foreign investment in Mongolia fell 17 percent to $3.9 billion in 2012, and in February this year, the country saw its lowest monthly inflow of foreign investment since at least 2010, according to the Mongolia International Capital Corporation.
"The SEFIL was one of the key factors holding foreign investors back," said Vidur Jain, an analyst at the local investment firm Monet Capital.
The amendment passed on Friday will exempt privately-owned foreign companies from the approval of parliament, but they will still need approval from both the minister of economic development and the department minister for the industry in which the company operates.
The approval process will be triggered by any transaction involving 33 percent or more of a strategic entity, according to the original law.
But the amendments also tightened the restrictions on foreign state-owned entities (SOEs), removing a 100-billion tugrik ($71 million) threshold triggering government intervention.
That means all foreign SOEs will need the approval of Mongolia's cabinet in order to buy into a Mongolian firm, regardless of the size of the stake.
For purchases of stakes of more than 49 percent, the approval of parliament will also be required.
Sereeter Javkhlanbaatar, an official in charge of foreign investment at Mongolia's Ministry of Economic Development, said on Monday that the country was now drafting an entirely new law designed to encourage direct foreign investment in sectors other than mining.
The foreign investment law, launched by a number of nationalist backbenchers in Mongolia's parliament last year, is widely believed to have been primarily targeted at state-owned firms from China.
Many politicians and citizens in Mongolia have been increasingly alarmed by their southern neighbour's growing economic hegemony, with China responsible for around 90 percent of the landlocked nation's export trade. (Reporting by Terrence Edwards; Editing by David Stanway and James Jukwey)
