# International Trade mechanics

When there is a case where a player wants to buy or sell something in a foreign country, first he has to buy Trade Visa of a country he wants these operations to happen in. 

Other countries\` markets are not visible until a player travels to the country of interest and for that he will also need a Travel Visa. 

Taxes from players buying and selling transactions are paid to the country budget and HEX owner depending on where they are made. Items bought by a player can be delivered via automated delivery system. 

Transportation tax has to be paid too. Transportation tax is paid to all the countries\` budgets in which the delivery is happening, and HEX owners of the starting point and ending point of delivery.
