The EU leaders, who meet in Brussels later on Wednesday, will step up sanctions because pro-Russian rebels in eastern Ukraine have not met their demands to end the violence there, the draft statement said.

The 28-nation EU has been under strong pressure from the United States and Ukraine to take a hard line against Russia.

The EU leaders will ask the bloc's bank, the European Investment Bank (EIB), to suspend financing of new public sector projects in Russia, the draft statement said.

EU countries will work together within the European Bank for Reconstruction and Development (EBRD) to suspend EBRD financing of new projects in Russia, it said.

EU diplomats say taking action at the EBRD will be complicated as Russia is one of 64 countries that are shareholders of the bank.

Russia has traditionally been the biggest recipient of the London-based EBRD's funds - the bank lent 1.8 billion euros ($2.44 billion) there last year. The EIB pledged to lend more than 1 billion euros to Russia last year.

The EU will broaden the scope of asset freezes to target companies and other organisations "that are supporting materially or financially actions undermining or threatening Ukraine's sovereignty, territorial integrity and independence," according to the draft statement.

If broadly interpreted, that change could have wide ramifications, potentially allowing the EU to target a range of Ukrainian or Russian companies.

The EU has so far imposed asset freezes on 72 people and two energy companies in Ukraine's Crimea region, which was annexed by Moscow earlier this year.

It has drawn up a list of hard-hitting sanctions on sectors of the Russian economy, but has held back from imposing them because some EU governments are wary of potential retaliation from Russia, the bloc's biggest energy supplier.

The EU leaders will also ask the EU's executive Commission to look into suspending EU bilateral and regional cooperation programmes that benefit Russia. Projects dealing exclusively with civil society will be excluded, the draft said.

Some 450 million euros of EU funding are set to flow to Russia between 2014 and 2020 under various cooperation programmes, according to the EU Commission.

The EU leaders will also ask officials to draw up proposals for further measure to restrict investment in Crimea, whose annexation by Russia is not recognised by the EU.

The leaders will say they expect international financial institutions not to finance any project that recognises the annexation of Crimea, according to the draft, which could still be changed following leaders' discussions.
