In 2023, Russia accounted for around 9% of our total cigarette and heated tobacco unit shipment volume, and around 6% of our total net revenues. Ukraine accounted for around 2% of our total cigarette and heated tobacco unit shipment volume, and around 1% of our total net revenues. Historically, we also produced finished goods in Ukraine for export and manufactured products in Russia. In 2022, as a result of Russia's invasion of Ukraine, we suspended planned investments and scaled down our manufacturing operations in Russia.
The full implications of the Russian invasion of Ukraine for our operations in those countries are impossible to predict at this time. The likelihood of retaliatory action by the Russian government against companies, including PMI, as a result of actions and statements made in response to the Russian invasion or otherwise, including the possibility of legal action against us or our employees; the deprivation of rights in, or access to, our Russian assets; or nationalization of foreign businesses or assets (including cash reserves held in Russia and intangible assets such as trademarks), is impossible to predict. We are continuously assessing the evolving situation in Russia, including regulatory constraints in the market entailing very complex terms and conditions that must be met for any divestment transaction to be granted approval by the authorities, and restrictions resulting from international regulations. In the event of a divestment, our ability to fully realize the value of the business would likely be subject to material impairment. In Ukraine, there is no way to know when and to what extent we will be able to fully normalize our operations or to what extent our workforce, facilities, inventory, and other assets will remain intact. These developments have and will continue to have a material adverse impact on our business, results of operations, cash flows and financial position, and may result in further impairment charges.
The conflict also continues to elevate the likelihood of supply chain disruptions, both in the region and globally, and may inhibit our ability to timely source materials and services needed to make and sell our products. For example, historically we sourced certain finished goods, production materials and components from both Russia and Ukraine, including printed materials and filters, and the invasion has, and may continue to, disrupt the availability of and impact our supply chain for these materials. These disruptions, to the extent we are unable to find alternative sources or otherwise address these supply constraints, may impact the availability and cost of our products in other markets, which would adversely impact our business, results of operations, cash flows and financial position, and may result in impairment charges. Furthermore, the imposition of various restrictions on transactions with parties from certain jurisdictions, the ban on exports of various products, and other economic and financial restrictions may adversely affect certain third parties with which we do business in Russia, such as customers, suppliers, intermediaries, service providers and banks.
The broader consequences of the invasion are also impossible to predict, but could include reputational consequences, further sanctions, financial or currency restrictions, punitive tax law changes, embargoes, regional instability, and geopolitical shifts as well as adverse effects on macroeconomic conditions, security conditions, currency exchange rates, and financial markets. Given the nature of our business and global operations, such geo-political instability and uncertainty could increase the costs of our materials and operations; reduce demand for our products; have a negative impact on our supply chains, manufacturing capabilities, or distribution capabilities; increase our exposure to currency fluctuations; constrain our liquidity or our ability to access capital markets; create staffing or operations difficulties; or subject us to increased cyber-attacks. While we will continue to monitor this fluid situation and develop contingency plans as necessary to address any disruptions to our business operations as they develop, the extent of the conflict's effect on our business and results of operations as well as the global economy, cannot be predicted.
The conflict may also heighten many other risks disclosed in this Form 10-K, any of which could adversely affect our business, results of operations, cash flows or financial position. Such risks could affect, without limitation, the achievement of our strategic priorities, including achievement of our RRP growth targets; the availability of third-party manufacturing resources; the availability of attractive acquisition and strategic business opportunities and our ability to fully realize the benefits of these transactions; our ability to attract, motivate, and retain the best global talent; and our loss of revenue from counterfeiting and similar illicit activities.
