Final answer:
The issue not specifically more complicated due to the international aspect of a transaction is legal systems, as legal challenges can also arise in domestic business. Issues like language differences, currency exchange rates, and import quotas are inherently more complex in international trade.
Step-by-step explanation:
Complications in International Transactions
When a transaction involves a buyer and a seller from two different countries, several issues can complicate the process. Language differences can lead to misunderstandings or require translations. Currency exchange rates affect costs and revenues since firms often incur costs in the currency of the nation where production occurs, but earn revenues in the currency of the nation where sales happen. Import quotas, which are government-imposed limits on the quantity of certain goods that can be imported, directly impact the volume of trade. Lastly, legal systems differ by country, and these differences can influence contract enforcement, regulation, and the overall legal framework within which businesses operate.
The aspect which is not more complicated specifically due to the involvement of two different countries would be the legal systems, as legal complexities can arise even in domestic transactions. Although international transactions can involve additional legal considerations, such as compliance with both domestic and foreign laws, the question asks for issues that are more complicated specifically due to cross-border transactions, and legal systems are intricate in both domestic and international contexts.
