Russian businesses are seeking more opportunities in China, despite differences in culture, geography and language. Our Moscow correspondent Dan Ashby takes a look at the challenges and opportunities they're facing.

China and Russia's leaders have a lot of business to discuss these days. This year, their mutual trade is expected to top one hundred billion dollars. But the numbers mask a simple fact: The majority of Russia's business with China is state-backed oil and gas sales. The challenge: how to get more businesses involved. Dima Kovpak teaches thousands of Russians how to do business in China, with all its idiosyncrasies.

DIMA KOVPAK CHINA BUSINESS COACH "China has grown a lot, in terms of scale of construction, technologies, the quality of produce. But in essence, it hasn't changed. When I come to biggest fairs, you still see Chinese people who don't speak English, who still take your orders on paper and give you a paper receipt. You can sign a short contract on your lap. But that would still have significance for the Chinese who are interested in cooperation."

Ironing out those sorts of cultural differences will be the challenge.

DAN ASHBY MOSCOW "It is 40 years since China's reform, and today the Chinese market is one of the biggest markets in the world. For years it has remained an enigma to Russian companies, but there are signs that is changing."

This firm is the first to import Chinese babywear to Russia. And they have global ambitions.

It is a small firm, but the hope is that others will follow. At stake for both countries, is a chance to develop new industries and commerce. Forty years on, the idea is to make sure those opportunities never stop opening up. Dan Ashby, CGTN, Moscow.
