Moscow - (AFP) - Russia warned Friday that sending new Western arms shipments to Ukraine would only "prolong" the conflict, ahead of a meeting in Washington between US President Joe Biden and German Chancellor Olaf Scholz.

"We note that the United States continues its policy aimed at increasing arms shipments to Ukraine," Kremlin spokesman Dmitry Peskov said.

He added that the handovers "will not have a decisive impact on the outcome of the attack (in Ukraine), but it is clear that they will prolong this conflict and have unfortunate repercussions for the Ukrainian people."

"This places a huge burden on the economies of those countries and has a negative impact on the well-being of their citizens, including in Germany," the Russian presidential spokesman added.

Joe Biden will receive German Chancellor Olaf Scholz in Washington on Friday, in what is considered an occasion to show unity in front of Moscow and Beijing.

According to the German Chancellor's spokesman, this meeting aims specifically to consult on developments in the conflict in Ukraine and the support that Kiev's allies can provide.

Western countries provide military support to Kiev to repel the Russian attack that began last year, and some, like Germany, provide advanced tanks.
