The world's top e-commerce platform, Amazon, seems to have nothing to do with the "blue ocean platform"? Actually, that's not the case. Many emerging sites are quietly attracting a large number of sellers to join. Although these markets may not be as large as the US site in terms of individual scale, they generally grow rapidly, have relatively less competition, and Amazon itself is investing a lot of resources to support them. They are excellent places to seek growth opportunities.

Currently, Amazon's emerging market sites include the Australian site, the Middle East site (Saudi Arabia site and United Arab Emirates site), the Indian site, and the Singapore site, etc. Many sellers have achieved further sales growth by expanding their business to these emerging sites.

According to Statista, in 2024, Amazon Australia's GMV reached 8.39 billion US dollars, with a year-on-year growth of 14%, making it the highest in the entire market. Additionally, the platform's download volume reached 1.23 million times that year.

The annual operation report released by Amazon's Middle East site indicates that the GMV of the Middle East site in 2024 has exceeded 18 billion US dollars, with a year-on-year growth of 67%, demonstrating a strong growth momentum.

Currently, new sellers who join the emerging sites of Amazon can receive a new seller introductory package. By combining multiple sites, the maximum commission reduction/sales return can reach up to 350,000 US dollars. For a single site, the advertising reward can be as high as 1,000 US dollars!

For the Middle East sites, Amazon has also launched the FBA Origin Refund Program. For each shipment of goods entering the FBA warehouses in Saudi Arabia and the United Arab Emirates, there is a cash rebate. The refund is available immediately upon shipment and will be credited to your account on a monthly basis!

03、rakuten.co.jp

It was established in 1997 and has been deeply rooted in the Japanese domestic market for nearly 30 years. Currently, it has over 100 million users, covering more than 80% of the Japanese population. Its user base spans various age groups and income brackets, with an annual sales volume of 17 billion US dollars.

In 2025, the GMV of Lotte's domestic e-commerce reached 6.35 trillion yen, with a year-on-year growth of 3.9%. Currently, the platform has over 57,000 premium stores. Although the total number of Chinese sellers is relatively small (about 1,000), Lotte is increasing its recruitment efforts for high-quality brands in China through the "1,000 Store Initiative", and the competition pressure is relatively low.

The entry threshold for joining Lotte is relatively high. Only enterprise entities can apply, and sellers with their own brands or authorized licenses and possessing Japanese language operation capabilities will be given priority. In terms of costs, sellers need to pay approximately 60,000 yen as an initial fee and a fixed monthly fee of 50,000 yen or more. The platform commission rate is usually between 8% and 12%.

04、coupang.com

Among the top 16 global e-commerce platforms, Coupang is the platform with an absolutely dominant market share in South Korea. It is renowned for its fast delivery service called "Rocket Delivery", which offers next-day or same-day delivery. Its traffic volume is approximately four times that of the second-place platform. It is the preferred platform for Chinese sellers to enter the South Korean e-commerce market.

In the entire year of 2025, Coupang's total revenue reached 34.5 billion US dollars, representing a year-on-year growth of 14%; among which, the net revenue from its e-commerce business was 29.6 billion US dollars, with a year-on-year growth of 11%.

The sellers can choose from two entry modes: One is that established sellers who have a strong market presence can register their own Korean companies; the other is that novice sellers can use the mainland business license to affiliate with a designated service provider to conduct local store business. The affiliate model has lower costs and enables quicker establishment of the store.

Currently, Coupang offers 90-day free storage fees, return fees, and disposal fees for returned goods, which directly alleviates the initial operational pressure. For the sold products, a commission ranging from 4% to 11% is charged based on different categories.

05、mercadolivre.com.br

The global top 17 e-commerce company Mercado Libre was founded in Uruguay in 1999. During its early stage, the company received a special financing of 7.6 million US dollars from well-known institutions such as JP Morgan. In 2007, it successfully listed on the Nasdaq, being the largest and most comprehensive e-commerce integrated service provider in the Latin American region.

In 2025, the total merchandise transaction value (GMV) of the platform will reach 65 billion US dollars, with a year-on-year growth of 26%. The sales volume will reach 2.4 billion items. Currently, the platform has over 1 million active sellers, and Chinese sellers, as the core of cross-border business, have reached tens of thousands in number, deeply participating in the global supply chain system of the platform.

In terms of product category performance, mobile communication, household appliances, computer accessories, and automotive accessories are the strong areas with high average transaction prices and significant demand on Mercado Libre. Due to the relatively scarce offline supply chain in the Latin American region, household living supplies, clothing and shoes, as well as sports and outdoor equipment have also shown extremely high growth potential.

The platform does not charge any entry fees, monthly or annual fees, or deposit. It only collects category commissions based on the completed orders. There are differences in commission rates for different sites, listing modes, and product categories. The regular category commission range is 10% to 20%.

It has achieved this through its strong localization strategy and technological foundation.

In the fiscal year 2025, the revenue of this platform reached 8.235 trillion rupees (equivalent to 9.8 billion US dollars), accounting for 47% of the entire Indian e-commerce market.

Currently, Flipkart does not directly open its platform to sellers from the Chinese mainland. You need to have a local Indian company as your entity, or apply for the Flipkart Global Sellers Program (the official cross-border program) using a company from Hong Kong or Singapore.

In terms of cost, this platform is highly competitive. It offers a policy of no entry fee and no monthly rent, and only charges a 4% to 15% sales commission after the transaction is completed. Moreover, the platform has launched a Chinese version of the backend, significantly reducing the operational barriers for Chinese sellers.
