1993 - Russia and Poland signed an agreement to build a 4,000km natural gas pipeline from northern Siberia across Polish territory to Western Europe. The pipeline, expected to be completed by 2010, will cost an estimated $10 billion (Dh36.78 billion) and is intended to ferry 67 billion cubic metres of gas a year from the Yamal peninsula in Russia’s Arctic north. The accord, signed by Polish and Russian Deputy Prime Ministers Henryk Goryszewski and Oleg Lobov, crowned a visit to Warsaw by Russian President Boris Yeltsin. Polish President Lech Walesa, standing beside him at Belweder Palace, hailed the accord as a symbol of improving economic ties between Russia and Poland.
