The EU, US and their allies have agreed to cut off a number of Russian banks from the main international payment system, Swift.
The assets of Russia's central bank will also be frozen, limiting Russia's ability to access its overseas reserves.
The intention is to "further isolate Russia from the international financial system", a joint statement said.
Russia is heavily reliant on the Swift system for its key oil and gas exports.
The joint sanctions are the harshest measures imposed to date on Russia over its invasion of Ukraine.

欧盟、美国及其盟国已同意将一些俄罗斯银行与主要的国际支付系统 Swift 隔离开来。
俄罗斯央行的资产也将被冻结，从而限制了俄罗斯获取其海外储备的能力。
一份联合声明称，其目的是“进一步将俄罗斯与国际金融体系隔离开来”。
俄罗斯的主要石油和天然气出口严重依赖 Swift 系统。
联合制裁是迄今为止对俄罗斯入侵乌克兰采取的最严厉措施。
Excluding certain Russian banks from the Swift system used for trillions of dollars-worth of transactions will hit the economy hard - and in the words of the White House, it will make the country rely on "the telephone or a fax machine" to make payments.
This is only a slight exaggeration. There are workarounds to Swift but none which are as efficient.
Only one country has been cut out in the past - Iran - which resulted in it losing 30% of its foreign trade.
Picking certain Russian banks will ensure the sanctions have the maximum impact on Russia, while preventing too much impact on Europe. European businesses will be able to continue to collect money owed and buy Russian energy.
Other measures are equally powerful. Curbs on Russia's central bank will stop it using its currency to limit the effect of sanctions.
Russia has been building up a cushion of foreign currency to protect its banks, but this new measure will significantly decrease the reserves available.
The impact of these measures may take a while to show - but they do express an immediate intent from Western nations.

将某些俄罗斯银行排除在用于价值数万亿美元交易的 Swift 系统之外，将对经济造 成 沉重 打 击，用白宫的话来说，这将使该国依靠"电话或传真机"进行支付.
这只是略微夸张。 Swift 有一些变通方法，但没有一个是有效的。
过去只有一个国家被切断——伊朗——这导致它损失了 30% 的对外贸易。
选择某些俄罗斯银行将确保制裁对俄罗斯产生最大影响，同时防止对欧洲产生太大影响。欧洲企业将能够继续收取欠款并购买俄罗斯能源。
其他措施同样强大。对俄罗斯央行的限制将阻止其使用其货币来限制制裁的影响。
俄罗斯一直在建立外汇缓冲以保护其银行，但这项新措施将大大减少可用储备。
这些措施的影响可能需要一段时间才能显现出来——但它们确实表达了西方国家的直接意图。
What have other leaders said about removing Russia from SWIFT?
Ukrainian President Volodymyr Zelenskyy urged the U.S. and other countries to cut Russia from the system. Some nations resisted the move out of concerns for the broader economy, but as the invasion wore on more European Union nations got on board.
Early Saturday morning, Italian Prime Minister Mario Draghi told Zelenskyy that Italy supported "Russia's disconnection from SWIFT, the provision of defense assistance."
Several hours later, Germany, which had been the last European Union nation holding out on the sanctions, offered measured support for Russia's disconnection from SWIFT, according to a joint statement from German Foreign Minister Annalena Baerbock and German Economics Minister Robert Habeck.
“We are working flat out on how to limit the collateral damage of a disconnection from #SWIFT, so that it hits the right people,” the officials wrote in a statement. "What we need is a targeted and functional restriction of SWIFT.”

其他领导人对将俄罗斯从 SWIFT 中除名有何看法？
乌克兰总统泽连斯基敦促美国和其他国家将俄罗斯从该系统中剔除。一些国家出于对更广泛经济的担忧而拒绝采取行动，但随着入侵的加剧，更多的欧盟国家加入了进来。
周六凌晨，意大利总理马里奥·德拉吉告诉泽连斯基，意大利支持“俄罗斯与 SWIFT 脱节，提供国防援助”。
根据德国外交部长 Annalena Baerbock 和德国经济部长 Robert Habeck 的联合声明，几个小时后，作为最后一个坚持制裁的欧盟国家，德国对俄罗斯与 SWIFT 的脱节提供了适度的支持。
官员们在一份声明中写道：“我们正在全力研究如何限制与#SWIFT 断开连接的附带损害，以便它打击正确的人。” “我们需要的是对 SWIFT 进行有针对性的功能限制。”
