The document was signed by Russian Transport Minister Igor Levitin, head of the Interstate Aviation Committee Tatyana Anodina and Polish Minister of the Interior and Administration Jerzy Miller.
Sergei Ivanov said that the signed document demonstrates Russia's unprecedented approach to the investigation of this accident.
"The deaths of 96 Polish people, including the respected Polish President, Lech Kaczyński, became our shared pain, a common tragedy which united our peoples," Sergei Ivanov said at the meeting with the Polish delegation. He added "right from the start our two countries have worked together like a well-oiled machine. There are no areas of misunderstanding between Polish and Russian experts, and I am certain none shall arise in future."
The Russian deputy prime minister also noted that the technical commission headed by the Interstate Aviation Committee had gone a great way towards deciphering all the data collected by flight recorders on board the Tu-154. "This work is now essentially complete," Sergei Ivanov said.
The deputy prime minister also stressed that "handing over copies of all this data to Poland does not mean the end of the investigation. Russian and Polish authorities will continue investigating the case."
He also noted that if Poland should, at some future point, require any other information falling outside the purview of the Interstate Aviation Committee, Russia stands ready to provide it. The deputy prime minister stressed that the public prosecution offices and investigation committees engaged in this case are independent bodies. "The Russian government will not interfere with their work," he said, adding that "Russia is no less eager than Poland to see the investigation continue and will do everything in its power to bring it to its logical conclusion."
Sergei Ivanov also stated that Poland might still receive the original recordings made by the "black box" flight recorders. "I do not exclude the possibility that in the future, following the conclusion of the investigation, the authentic, original recordings will be handed over to Poland," the deputy prime minister said.
Jerzy Miller said that Poland valued Russia's professional and efficient investigation into the accident. "I would like to thank you for your flexible approach to this matter and your readiness to share documents relating to this case with us," the Polish minister said. "This is the first time that we have seen such an approach taken anywhere in the world," Jerzy Miller stressed.
