Introduction
The issue of money laundering which is popular referred to as “money cleaning” is an international headache. The extent to which money is laundered globally is estimated to be between $500 billion and $1 trillion. Money laundering is the movement of funds for the purpose of concealing the true sources, ownership, or use of the funds. The source of the funds can be criminal activities such as drug trafficking, arms sales, embezzlement, extortion and ransom among others. Alternatively, the source of funds can be legitimate, such as donations to charities or non-government organizations.（Imm Yun-bin，2008）In assessing the international concern of money laundering, one would remember that The United Nations Convention against Illicit Traffic in Narcotic Drugs and Psychotropic Substances, adopted in December 1988 in Vienna, was the first international instrument to address the issue of proceeds of crime, and to require countries to establish money laundering as a criminal offence. Since the end of the 1980's, countries have endeavored to establish these alert mechanisms, to ensure that criminal assets can be identified, seized, and confiscated wherever they are.（Aidan Sausner，2007）U.K is the first country to enact laws on anti-money laundering, and now it has relative perfect law system in the world, although it still has problems in fight against money laundering. China starts lately in the establishment of money laundering law. But china intensified efforts to improve its anti-money laundering regime by passing an anti-money laundering law in 2006 and issuing many rules later. This essay firstly gives a definition of money laundering, and then describes detailedly the money laundering law both in China and U.K. As for China, it gives a specific description on the legislative course and anti-money laundering law system.

Finally, this essay compares U.K‘s law system with China’s. The differences mainly cover three hands.
