    The People's Republic of China has initiated an overhaul of its social security system, reformed the personal taxation regime and has extended the scope of these laws to foreigners residing in China.

    The Kingdom of Morocco is supporting the ambition of becoming the leading financial place for Africa. In this context, a wave of draft laws is to be passed and implemented within the following months, amongst which, the Law No. 53.08, setting up a new financial authority, and the Law No. 54.08, reforming public offering rules, are of paramount importance to Moroccan and foreign issuers, and financial institutions.

    The opportunities offered to foreign investors by the Chinese mergers and acquisitions market are increasing every year: in 2010, transactions involving foreign companies came to 60.1 billion euros, an increase of 21.2% compared with 2009. Seen from the West, where markets are declining, all sectors of the Chinese economy seem to be undergoing promising development and the statistics indicate that the Middle Empire will be a lasting springboard for growth.
