Good starting points are trade and industrial fairs and exhibitions, where you can meet potential clients and partners, sales representatives and distributors. Another useful route is to join trade delegations organised by government agencies or international chambers of commerce.
Most business is conducted in Istanbul, Turkey's commercial metropolis.
Ankara, the capital, is more important when dealing with public authorities or government. A local business person who can act as your agent or liaison officer is the best bet. Turkish hospitality is renowned and your business partner is likely to put business on a personal level. Small talk plays a vital role when conducting business. Topics will include your arrival, your accommodation and how you find the country.
