Siemens announced the plan in November but put it on hold, as it was formulating a restructuring plan.
The company has received the backing of German Chancellor Angela Merkel in its attempt to acquire Alstom's (ALSMY) power business. However, Merkel also said the decision is a corporate one and so she "will not get involved in that." French President Francois Holland said his government is still waiting for Siemens to makes a detailed offer.
