Now that the whole world spoke Chinese, could they communicate in Chinese when they went to Europe and America?

In the context of the current global economy, more and more people began to learn Chinese and use it to communicate. Although Chinese has become a very popular language in some European and American countries, there may still be many people in other places who are unfamiliar with Chinese or can't use it. In this case, if you want to communicate with the locals, it is best to use English or other major languages to ensure smooth and accurate communication. Of course, if you are proficient in Chinese and are interested in the local culture, you can also try to communicate in Chinese, but you need to pay attention to respecting the local culture and social customs.
