1. Russian companies moving into Asian markets are often attracted to China primarily for its growth and size. But increasingly they are finding that investment opportunities in Southeast Asia are too good to be ignored and making the move. The future of Russian business will depend not only on Russia attracting international players to its markets, but also on Russian companies making greater inroads internationally. Russian corporates are increasingly taking this step. Only a decade ago it was only Russian energy giants, or resources producers, that had moved into the global marketplace. But more and more, they are being joined by infrastructure and construction companies, machinery and equipment manufacturers and lessors, and Russian mobile telecommunications operators. More Russian corporate players can be expected to follow.
2. When Russian companies step into a global marketplace, they find many of the same challenges and issues that international players coming to Russia find. The laws and customs and systems are different. The Russian companies looking to move into markets in Asia and Europe, and in emerging markets, will need to understand a different business culture and legal framework, and ensure they have good advice on how best to work in that marketplace.
3. The attractions of Southeast Asia are the rapidly growing economies of the region, which have posted strong economic growth as the major developed economies have remained mired in debt and weak demand following the global financial crisis of 2008. I fact, Southeast Asia is projected to grow at a robust 5.5 percent, supported by strong national savings rates, a focus in domestic demand, and an increasingly sophisticated workforce. Beyond the traditional leading regional economies of Singapore, Malaysia and Thailand, Indonesia, which is setting ambitious infrastructure investment as the cornerstone of its economic growth plans, and Myanmar, which is coming in from decades of economic isolation, are getting increasing attention.
4. The experience of companies moving into the Southeast Asian market, regardless of the country, has demonstrated the value of developing a very good understanding of the market. It is known that one of the most important first steps is to get good local advice. Not only legal advice, but general advice to assist in navigating the applicable country, political and legal risks. Many businesses and clients try to replicate their business models from home in Asian markets, and sometimes it doesn't work. So potential investors have to do a lot of research into the way things work in the relevant jurisdiction and not just try to use the same business models that have been successful elsewhere.
5. One part of the knowledge acquisition process is about getting effective advice from legal and other advisers, but obviously it also includes making an effort to meet as many people as possible. Japanese companies often open a representative office in the country and spend quite some time just meeting people, talking to people and finding out what the legal climate is, as well as who might be a suitable local partner.
