Asian shares edged higher on Monday, with investors wary of a deepening crisis in Ukraine and a downbeat China manufacturing survey, while the euro touched a fresh one-year low ahead of this week’s European Central Bank meeting. Ukrainian President Petro Poroshenko warned a “full-scale war” was imminent if Russian troops continued to advance in support of pro-Moscow rebels, while U.S. MSCI’s broadest index of Asia-Pacific shares outside Japan shrugged off early losses and was up about 0.3 percent, moving back toward Thursday’s six-and-a-half-year peak.
