Facing the short supply of timber, China must actively improve the sustainability of its timber import from Russia. Therefore, this paper evaluates the state of China-Russia timber trade in 2002-2016, in the context of the construction of the China-Mongolia-Russia (CMR) economic corridor. Drawing on the Markov theory, the Grey prediction model was revised to predict the trade value, log volume and sawn timber volume of China's import of Russian timbers in 2017-2025. The results show that the revised Grey-Markov model was 4.53%, 2.23% and 30.08% higher than the Grey prediction model in the prediction accuracy of trade value, log import volume, and sawn timber import volume between China and Russia, respectively; that the import value will increase to USD 5.047 billion in 2025, the import volume of sawn timbers will grow steadily in 2017-2025, while the import volume of logs will decline to 6.8025 million m 3 in 2025; these trends are mainly the result of the hike in log price and tariffs in Russia. Based on the predicted results, the authors discussed about the mechanism of China-Russia timber trade, and then put forward several suggestions: both countries should pursue sustainable development, highlight the importance of infrastructure construction, establish trade associations, cultivate a favourable investment environment, and encourage technological innovations. The research findings shed new light on sustainable development in the fields of forestry and trade.
