China's top ecommerce website Taobao and Yahoo Japan have partnered to launch two online platforms to cross sell in each other's markets.

The partnership will allow Yahoo Japan merchants to list some eight million items in a Chinese-language TaoJapan section.

Taobao, a subsidiary of ecommerce firm Alibaba group, will offer 50 million products from China to Japanese consumers on Yahoo Japan's China Mall. The two platforms will launch on June 1.

"We are pleased to help Japanese small businesses sell their products to China on our Taobao platform as we believe more choice is a good thing. As a result of this initiative, our respective customers will eventually be able to choose from millions of products from China and Japan," said Jack Ma, chairman and CEO of Alibaba Group.

"In addition to providing our respective consumers with broader choices, both Alibaba Group and SoftBank also understand the power of e-commerce to change the fortunes of small businesses for the better and that's why we have decided to create a solution that brings about benefits for both the small businesses and the consumers in China and Japan, and around the world."

Taobao and Yahoo Japan expect the new offerings will create jobs by helping to increase small business growth through ecommerce and by opening markets for goods and services for domestic merchants by creating access to overseas sales.

Taobao and Alibaba Japan will jointly operate TaoJapan. Taobao will operate the website and Alibaba.com Japan will act as a fulfillment service provider for Yahoo Japan China Mall.

Alibaba.com Japan is a joint venture between Alibaba.co and SoftBank Corp.

"We expect that the Asian economy will continue to grow further led mainly by China and Japan, and that the Internet business and e-commerce business will be the core of that growth," said Masayoshi Son, chairman and CEO, SoftBank Corp, and chairman of the Board, Yahoo! Japan Corp. SoftBank is the largest shareholder in Yahoo! Japan with a nearly 41 percent interest.
