Experts also pointed out that the Japanese government has committed itself to widespread economic investment in both reconstruction and economic development and post-earthquake, again providing excellent opportunities for cash-rich Chinese companies.
In July, the Japanese government also revealed its mid- to long-term growth strategy for the country, entitled "Japan Revitalization Strategy", targeting average annual growth of 3 percent until 2020, from last year's earthquake, tsunami and nuclear accident.

"The Japanese market itself is not attractive for us, but we could certainly partner with our Japanese counterparts to seek new business opportunities for our engines worldwide, for instance," said Zhao from the CSR.
"Partnerships like those are win-wins for both sides."

Since June 1, China and Japan have started direct trading of their currencies, the first time that China has allowed a major currency apart from the US dollar to trade directly with the yuan, in a move that is expected to boost their bilateral economic ties.
So far, transactions between the two currencies are "smooth and sound", according to Xiao, operating at an average daily volume of about 30 billion yen.
