BRUSSELS - European Union leaders are likely to threaten Russia with new sanctions over Ukraine on Saturday but, fearful of a new Cold War and self-inflicted harm on their own economies, should give Moscow another chance to make peace.
At a summit in Brussels that may hand one of the Union's top jobs to Poland's premier and give hawkish Kremlin critics in ex-communist Eastern Europe new influence in the bloc, EU officials gave Ukraine's embattled President Petro Poroshenko a warm welcome and assurances of further economic and other support.
