Final answer:
The language barrier is a cultural hurdle that may hinder China from becoming a vast market in the long run.
Step-by-step explanation:
The cultural hurdle in the path of China becoming a vast market in the long run is the language barrier. China's logogram-based language poses a challenge for the development and diffusion of technologies designed for alphabet-based systems. This creates a barrier for global companies to enter and establish themselves in the Chinese market due to the difficulty in adapting their products and services to the local language.
Culture lag can also contribute to slowing the expansion of markets. The term refers to the time between the introduction of new technology or ideas and their adoption within a society. This can lead to tangible issues such as outdated infrastructure unable to support modern demands, indicating that cultural adaptations and technological updates are necessary alongside economic policies to support a robust market growth.
