The constitutional reform in Ukraine is the basis for comprehensive changes in the country, Germany's Ambassador to Ukraine Christof Weil has said.

"The constitutional amendments are the key to ambitious reforms launched by Ukrainians two years ago," the ambassador said in Kyiv on Friday while addressing a public forum on the constitutional reform in Ukraine.

"The constitutional reform is the ground for the comprehensive changes Ukraine must pass as a state, also including from the position of society and economy," he stressed.

Weil says that such constitutional reforms are needed for building a democratic state and society in Ukraine.

In his words, the Ukrainians have to see the results of the reform, but "the issue of federalization, I think is very difficult to understand as a term, [it is] poisonous to perception by the Ukrainians". "We must be aware that it is the issue of subsidiarity both for citizens, and for municipalities, and this is a prerequisite for the functioning of other state institutions," Weil said.

The ambassador also expressed an opinion that the reform of justice is the "be-all and end-all in the fight against corruption."

"Despite the current difficult economic period, I know there are German businessmen who are willing to invest in Ukraine. I know such enterprises and businessmen," he said.

According to the ambassador, "it is not the war in the [country's] east that is a major obstacle for German investors – their major nightmare is the fact that they will have to deal with Ukrainian court sometime in future," he said.

In this context, he stressed the importance of the reform of the judicial system as one of the elements of attracting investments to Ukraine.

"The possibility of bribing a court has to be eliminated once and for all," he added.
