The state-owned firm and its units have been upping their presence in Russia over the last few months as Dubai World seeks to tap into Europe's most populous country.
"Dubai World has recently been exploring major investment possibilities in marine terminals, logistics and rail transport with Russian partners," it said in a statement after concluding meetings with a Russian delegation.
Dubai World's port and free zone subsidiary has signed an agreement with Russian Railways to study the development of supply chain infrastructure in Russia, Dubai World said in the statement.
Limitless, one of its real estate units, in February agreed to build a new city near Moscow.
DP World also jointly operates the Vostochny International Container Services terminal on Russia's far eastern Pacific coast.
