The document was signed after the presidents met in the Kazakh capital of Astana, where Putin arrived on Wednesday for a two-day official visit.
Following the talks, Russia and Kazakhstan adopted a protocol on the resumption of a bilateral agreement on trade and economic cooperation that renews Russian oil and oil product exports to Kazakhstan.
Kazakh Energy Minister Almasadam Satkaliyev and Russian Energy Minister Sergei Tsivilev exchanged the protocols during a signing ceremony, a Sputnik correspondent reported.
Russian President Vladimir Putin said on Wednesday that he had discussed the interaction between Russia and Kazakhstan in detail with Kazakh President Kassym-Jomart Tokayev and exchanged views on international and regional issues.
"We discussed in detail a wide range of issues pertaining to bilateral interaction in the political, economic and humanitarian spheres, exchanged views on the most pressing regional and international problems," Putin said.
Putin said that the increasing use of national currencies between the two countries protects operations from external influences.
"The share of national currencies in mutual settlements accounts for almost 90%, which allows to shield commercial operations between the two countries from the negative impact of external factors, including political conditions," Putin said.
The Russian president also said that Kazakhstan had received an invitation to obtain the status of a partner country in BRICS.
Increase of Mutual Payments in National Currencies
Putin and Tokayev welcome the increase in the share of mutual payments in national currencies, which will contribute to strengthening financial sovereignty, according to joint statement released on Wednesday.
