BEIJING, Oct 26 (Reuters) - The dollar should remain the principal currency in China's $2.27 trillion stockpile of foreign exchange reserves, but the share of the euro and yen should increase, an opinion piece in the Financial News, a paper published by the People's Bank of China, said on Monday.
The article did not give the title of the author, Zhou Hai, and the central bank's automatic telephone operating system did not recognise his name.
Zhou also said China should improve the yuan's exchange rate mechanism to reduce pressure on the central bank to buy inflows of foreign exchange.
The article appeared on the "Theoretics Weekly" page of the paper. Many other researchers have expressed similar views.
Zhou said China should exclude the Hong Kong dollar from its official reserves because Chinese can easily obtain the currency and it is pegged to the U.S. dollar. (Reporting by Zhou Xin and Alan Wheatley; editing by Ken Wills)
