More than 50 agreements will be signed during Chinese Premier Li Keqiang's visit to Russia, Andrey Ivanovich Denisov, Russia's ambassador to China, said on Friday.

"They will cover bilateral cooperation in areas including energy, finance, aerospace and agriculture," said the ambassador two days before Li's visit.

Among the 50 agreements, some 30 are signed by government departments, with a joint communique to be signed by the premiers of the two countries being the most important.

The other 20 agreements touch on projects such as high-speed railway construction, joint production of commercial aircraft and heavy-duty helicopters.

Noting the current relationship between China and Russia as "the peak", however, Denisov said there are bound to be a few problems when carrying out these projects.

"Even the happiest family in the world has problems to solve sometimes," the ambassador said, "but I believe Russia and China have developed an effective system for solving any problems that could possibly occur."
