China's seaweed sandwiches are primarily sold in the domestic market, where they have gained popularity as a healthy and convenient snack option. However, China is also a major exporter of seaweed products, including seaweed sandwiches, to other countries and regions.
According to industry reports, some of the main export markets for Chinese seaweed products, including seaweed sandwiches, include Japan, South Korea, the United States, and European countries such as France and Germany.
Japan and South Korea have a long history of using seaweed in their cuisine, and as such, they have a large market for seaweed-based products. The United States and European countries have also seen growing demand for healthy and sustainable food options, which has led to an increase in the popularity of seaweed-based products.
In addition to these countries and regions, Chinese seaweed sandwiches may also be sold in other markets, depending on the specific distribution channels and marketing strategies of individual manufacturers and distributors.
