An unending stream of people — mostly women and children — has poured into neighboring countries, especially Poland.Western allies have imposed unprecedented sanctions against businesses, banks and billionaires in a bid to choke the Russian economy and pressure Moscow to halt its assault.'Neutralization' of UkraineBut Putin has equated global sanctions with a declaration of war, put nuclear forces on alert and warned that Kyiv is "putting in question the future of Ukrainian statehood" by continuing to resist.Moscow has been forced to restrict sales of essential goods to limit black-market speculation, while on Sunday payment giant American Express halted operations there, a day after Visa and MasterCard announced similar steps.Streaming giant Netflix suspended its service in Russia while social media titan TikTok halted the posting of new videos from Russia.Despite harsh punishments for those voicing dissent, protests in Russia against the Ukraine invasion have continued, with more than 10,000 people arrested since it began.Putin has pledged the "neutralization" of Ukraine "either through negotiation or through war."Sputtering diplomatic efforts to resolve the conflict continue with the foreign ministers of Ukraine, Russia and Turkey set to meet in southern Turkey on Thursday, Ankara said.China said on Monday it was open to helping to mediate peace, but stressed that the friendship between close allies Beijing and Moscow remained "rock solid."The International Court of Justice meanwhile heard Ukraine's appeal for it to order Russia to halt the fighting, but Moscow declined to attend the sitting of the UN's top court, in The Hague.NATO allies have so far rebuffed Ukraine's calls for a no-fly zone, with one senior U.S.
