(Adds details from the court ruling)
MADRID/HONG KONG, Sept 11 (Reuters) - Spain has launched an investigation into the European management of the Industrial and Commercial Bank of China (ICBC) in Luxembourg as part of a widening probe into the alleged laundering of hundreds of millions of euros through the Chinese banking giant's Madrid branch.
A Reuters investigation in July revealed Spanish prosecutors were poised to explore the role of ICBC Luxembourg in the alleged money laundering scheme following the arrest of seven ICBC executives in Madrid in February last year, including branch manager Liu Wei and the general manager of the bank's European division, Liu Gang.
The Spanish High Court said on Monday it had approved a request from the anti-corruption prosecutor's office to investigate ICBC's European headquarters for the alleged crime of money laundering.
High Court judge Ismael Moreno ruled that ICBC's Europe board must name a representative and a lawyer to be summoned to appear before the court.
"ICBC Luxembourg was aware at the time of the way ICBC Spain was operating, and the Luxembourg headquarters provided it with internal audit services," the ruling said.
The Luxembourg unit of ICBC holds the lender's European Union bank licence and is responsible for supervising the Madrid branch.
According to the court ruling, ICBC Europe could face a fine, asset seizures or dissolution if found guilty.
An ICBC spokesman in Luxembourg was not available for comment on Monday.
The Reuters' investigation drew on thousands of pages of confidential case submissions and interviews with investigators and former ICBC employees to show how a long running investigation into alleged Chinese organised crime networks eventually led Spanish police to mount an early morning raid on ICBC's Madrid branch on Feb. 17 last year.
At the core of the ICBC case is the relationship between the bank and a group of clients from Spain's thriving Chinese business community. These Chinese clients are alleged to have accumulated mountains of cash, much of it from avoiding duty and tax on the sale of consumer goods imported from China.
Spanish judicial officials told Reuters that between 2011 and 2013, ICBC's Madrid branch transferred about 225 million euros to China, most of it for suspected criminal networks. These networks also sent funds via money transfer firms in Spain and by smuggling large amounts of cash by road to other European countries from where it was transferred to China.
In response to the Reuters' investigation, a spokesman for ICBC in Europe said in July the bank was a "law-abiding company" and had cooperated with Spanish authorities. The case file, he said, was sealed by the court so the bank could not comment.
On Monday, the Spanish High Court ruling said criminal responsibility for the alleged money laundering extended to the bank's European headquarters, ICBC Luxembourg.
"The directors Liu Gang and Liu Wei have acted under ICBC Luxembourg's authorisation, and in benefit of ICBC Luxembourg, seeking to capture the maximum number of cash deposits from clients, of which a great majority were involved in activities in the black economy and are suspected of tax and customs fraud," the court said.
"The opacity of the funds was increased by dividing up the transfers they were making, by using internal unnamed bank accounts, by the use of falsified documents and identity cards, fake invoices, and massive transfers to China."
Liu Wei and Liu Gang did not respond to requests for comment.
The court ruling said between 2011 and 2014 Spanish authorities did not detect any lending or mortgage activity at the Madrid branch.
"Therefore, it can be concluded that between 2011 and 2014 there was no banking activity other than capturing money from criminal groups to which it was providing banking services to conceal their earnings and transfer them to China," the court ruling said.
The court said ICBC had received 148 million euros in cash in 2011, 73 million euros in 2012, eight million euros in 2013 and 281 million euros in 2014. (Editing by Peter Hirschberg and Mark Potter)
