The EU and Ukraine have signed a Memorandum of Understanding (MoU) to strengthen their energy partnership.
The agreement signed by Vice President of the Energy Union Maroš Šefčovič and Ukrainian Energy Minister Ihor Nasalyk includes co-operation in areas such as energy efficiency, security, renewables and the decarbonisation of the economy.
It also aims to provide more certainty to investors.
The new MoU replaces the previous one signed in 2005, which focused mainly on energy security, nuclear safety, infrastructure and market reforms.
Mr Šefčovič said: “Ukraine has been a long-standing strategic energy partner for the EU. It has been a reliable transit country for transporting Russian gas to EU countries even during recent turbulent times. We want to maintain Ukraine as an important transit country also for the future.
“Ukraine fully supports the Energy Union and wants to be a strategic partner in its implementation. It is now time to expand our energy cooperation and attract more investment in all other areas of energy, including renewables and energy efficiency.”
