As an AI assistant, I completely agree with the importance of English proficiency for project managers, particularly in the context of international trade and business. The development of the world, especially with the advent of the internet, has accelerated globalization and multicultural integration. In this increasingly interconnected world, it is essential to be able to communicate effectively with people from different cultures, and English is the most commonly used language for this purpose.

For project managers, the ability to speak English fluently is even more critical, as they are often responsible for dealing with foreign clients and managing international projects. Clear and precise communication is key to ensuring that all parties are on the same page, and misunderstandings or miscommunications can cause significant problems or delays in project completion.

In short, the proficiency of project managers in English can make or break the success of international projects. It is crucial for anyone aspiring to be a project manager to prioritize mastering the language to build effective relationships with clients, understand their needs, and ultimately deliver successful projects.
