NATO's multifaceted assistance package for Ukraine will be financed through special trust funds and bilateral programs, Ukrainian President Petro Poroshenko has said.

"Never in the history of NATO has such significant assistance been rendered to a country. This represents support in 40 spheres – including security, operation integration, as well as in the defense sector. The assistance will be rendered via special trust funds. The landmine removal fund was opened today, and the bilateral program has begun to operate," Poroshenko said on Saturday during at a press conference with NATO Secretary General Jens Stoltenberg.

Ukrainian Foreign Minister Pavlo Klimkin commented on the NATO assistance package, which can be easily used.

"Ukraine will receive a multifaceted assistance package from NATO. It is comprised of 13 main programs and 40 projects to render concrete assistance. The document is changeable and will be augmented by NATO and NATO members, who give Ukraine as much as it can EFFECTIVELY use," Klimkin wrote on his Twitter account on Saturday.

Klimkin said that NATO will provide strategic coordination of the assistance programs and the sides will work to reform Ukraine's defense and security sectors to bring them in line with NATO standards.

"I think that most of the work in the assistance package will be completed by 2020, that is, in four years," Klimkin said.
