MOSCOW, March 19 (Reuters) - Russian aluminium giant Rusal 0486.HK has returned to a plan to resume a bond issue worth 500 million yuan ($69.16 million) that was cancelled in late February after an EU embargo on aluminium imports from Russia, a financial market source told Reuters.

Rusal plans to collect bids next week, the source said.

Rusal, the world's largest aluminium producer outside China, last week assessed the impact of the latest EU sanctions as "not significant for the group."

It warned, however, that ongoing geopolitical uncertainty, including sanctions imposed by the United States, European Union and other countries, may result in "significant limitations" for sales channels, the availability of raw materials for production and its supply chain.

The European Union banned primary aluminium imports from Russia as part of a 16th sanctions package against Russia but introduced a quota for aluminium imports from Russia of 275,000 tons for a 12-month period to ease the transition.

Hong Kong-listed Rusal has since indefinitely postponed its plans to offer investors bonds worth 500 million yuan with settlements in roubles, declining to comment substantively.

Analysts linked this step to the risk of weak demand for Rusal's securities immediately after the new package of European sanctions.

Rusal, which is not subject to direct Western sanctions, has been seeking to diversify sales towards Asian markets.
