KYIV, July 27 – Conditions for investing into the oil and gas sector of Ukraine have improved in the past years, although for boosting production the country should hold tenders to sell new licenses and attract respected international advisors, Head of Office of the National Investment Council Yulia Kovaliv said.

"For the correct organization of tenders and licensing rounds, it is necessary to attract advisers to properly create and do marketing," she said in an interview with Interfax-Ukraine.
