The story
The agreement between Romanian gas company Transgaz and Hungarian oil and gas company MOL was signed on 1 July 2008. The intergovernmental agreement to build a natural gas pipeline between countries was signed in May 2010 in Arad. The pipeline was supposed to be inaugurated on 29 July 2010 but was postponed until September due to construction issues on the Hungarian side. The pipeline is supposed to be inaugurated by the European Commissioner for Energy Günther Oettinger.
