What is a key characteristic of contracts under the Vienna Convention?

Contracts under the Vienna Convention, formally known as the United Nations Convention on Contracts for the International Sale of Goods (CISG), are explicitly designed to facilitate international trade. This international treaty establishes a uniform framework for buyers and sellers from different countries, promoting fair and effective commercial relations. By reducing legal barriers and creating a common set of rules, the Convention aims to enhance the ease of conducting cross-border trade, thereby making it simpler for parties to engage successfully in transactions without the complexities of differing national laws.

The other options reflect misunderstandings of the Convention's purpose and structure. Local law does play a role in supporting the application of the Convention, but it is not the primary basis for contracts under it. There is also no strict requirement for a specific format; rather, the Convention emphasizes the importance of mutual agreement and intent. Enforcement mechanisms do exist within the framework of the Convention, as it provides guiding principles and legal recourse for parties wishing to enforce their contracts internationally.
