"Ukraine is being pumped with armaments, meaning, direct supplies, future contracts, and, as you see, these are multi-million, billion contracts as a whole. It is about dispatching there militants disguised as instructors", Zakharova told the Russia broadcaster Krym 24.
Over the past several weeks, Kiev and some Western countries have accused Moscow of amassing troops near its border with Ukraine.
Moscow, for its part, has repeatedly rejected the accusations saying that the West wants to use them as an excuse to deploy NATO military equipment near the Russian border.
The US State Department said on Saturday that Assistant Secretary for the Bureau of European and Eurasian Affairs Karen Donfried will visit Moscow and Kiev from 13-15 December and will then meet with EU representatives in Brussels to discuss a diplomatic resolution of the situation in Ukraine.
While US President Joe Biden outlined that Washington never planned to send troops to Ukraine, the White House still warned Moscow that there would be consequences in the event of any aggression.
Following a meeting in Liverpool, the G7 foreign ministers of Canada, France, Germany, Italy, Japan, the United Kingdom, and the United States, along with the High Representative of the European Union, echoed the sentiment. The ministers pledged that Russia would face a "severe cost" in the event of any military aggression in Ukraine.
The statements come amid Kiev announcing that the US, along with the Ukrainian border service, having launched an initiative to strengthen the country's eastern and northern borders, with Washington set to pour $20 million into the project. It was also revealed that Biden had prepared $200 million in military assistance, but postponed delivering it in order to allow more time to resolve the ongoing crisis on the border between Ukraine and Russia.
