The energy sector in Asia-Pacific countries is currently undergoing a transformation. This is explained by the gradual transition to a post-industrial development model, which involves a gradual increase in the share of the service sector (as a percentage of GDP), as well as the urbanization of the population. This ultimately leads to an increase in the consumption of not only liquid hydrocarbons but also natural gas, particularly in transport and the electric power sector. While some Asia-Pacific countries have reached or are already approaching their peak in liquid hydrocarbon demand (with the exception of low-income countries such as India), the peak in gas demand will occur in the 2040s and 2050s. Given the shortage of natural gas to meet the needs of their domestic markets, Asia-Pacific countries are interested in increasing gas supplies from Russia. Moreover, the main demand will be concentrated not only in China and India, but also in ASEAN countries. This article examines Russia's cooperation with the Asia-Pacific region in the supply of both pipeline gas and Liquefied Natural Gas (LNG). The most promising way to increase exports in the long term may be through increased LNG supplies, particularly to ASEAN countries. However, to increase exports of this type of gas, Russia needs to address a key issue: the construction of tankers under the Russian flag.
