Ukraine's interim government said Wednesday that Russia has also amassed 80,000 troops along its border with Ukraine. Russian officials denied that accusation, as they have reports and video evidence of Russian forces flooding into the Crimean peninsula ahead of a controversial referendum on the region's future set for Sunday.
"We have to recognize, even though we will continue to move forward with this attempt to form a contact group, that we've made no progress," Merkel told reporters at a joint news appearance with Tusk in Warsaw.

Sunday's referendum in Crimea -- a strategic, largely Russian-speaking area that is home to 2 million people -- asks voters whether they want to secede from Ukraine and become an independent country.
The pro-Moscow regional government installed by Russian gunmen two weeks ago had originally planned to ask voters whether they wanted Crimea to be annexed by Russia. However, the referendum wording was revised Tuesday, apparently in an effort to shield the Kremlin from the consequences of engineering a transfer of a sovereign country's territory in breach of the U.N.

Merkel and Tusk also called for Ukraine to sign the European Union association agreement that was the catalyst for a three-month rebellion against former President
Putin and the Kremlin-controlled Russian media have cast the uprising against Yanukovich as an unconstitutional overthrow of an elected leader done at the urging of meddling Western states. Russia continues to describe the political opponents of Yanukovich now running the Ukrainian government as fascists and ultranationalists and contends the troop deployments in Crimea represent local efforts to protect Ukraine's Russian minority and key military installations.
Russia bases its Black Sea fleet on leased territory in the Crimean port of Sevastopol.
Ethnic Russians comprise about 17% of Ukraine's 46 million population, and about one in four claim Russian as their mother tongue. Ethnic Russians are concentrated in the eastern and southern areas of Ukraine. In Crimea, which was part of Russia for centuries before 1954, they are a majority.
