Eastward push

The European Union prepares to sign aid and trade agreements at a Vilnius summit with several East European countries, angering Russia.

The EU Association Agreements could frustrate Moscow’s effort to form a Eurasian Union of former Soviet satellites benefiting from cheaper Russian energy.

Ukraine wants an Association Agreement, but Russia is turning up the pressure on the country, which is dependent on Russian gas.

Who wins and who loses in this brewing commercial cold war? And what’s in it for the EU, to boost aid and trade to its eastern neighbours?
