目前为止，大概38个国家对俄罗斯拥有或运行的飞机关闭了领空，英国，加拿大，欧盟，瑞士的制裁手段基本相同，因为纽约伦敦金融市场的地位，再加上俄富豪的财富主要藏在英美所以金融制裁威力相对较大，以下是从bbc转来的美国目前的制裁措施。除了以上国家外，芬兰瑞典日本韩国澳大利亚新西兰新加坡也加入制裁。中立国家瑞士奥地利也参加了制裁。
Here's what the US has committed so far:
- Release of $350m (£263m) worth of weapons to Ukraine
- Supplies worth $54m (£41m) in humanitarian assistance
- Removing selected Russian banks from the global Swift messaging system
- Restricting the Russian central bank from defending the rouble
- Joining a trans-Atlantic task force to freeze and seize oligarchs' assets
- Closing off US airspace to Russian owned and operated aircraft
The White House has also asked Congress for an additional $6.4bn (£4.8bn) in emergency assistance over the next few months.
However, Biden again emphasised that the US would not send troops to engage with Russians in Ukraine.
