More Dialogue and Further Development

In January 2008 Slovenia took over the six-month rotating Presidency of the EU Council and this is the first time since the wide EU expansion in 2004 that a new member state bears this responsibility. China is Slovenia＇s most important trading partner in Asia and in the past few years the turnover between China and Slovenia has been increasing steadily. Since 1992, China and Slovenia have maintained high-level contacts and regular dialogue. In November 2007, Slovenian Prime Minister Janez Jansa paid a visit on the state level, which was very successful and provided a new push for further strengthening of bilateral ties. This year marks the 16th anniversary of the establishment of diplomatic relations between China and Slovenia.

政府审计信息公开基本理论问题研究：涵义与分类

政府审计信息公开是腐败治理的重要途径。政府审计信息是审计机关控制的并反映所有政府审计关系人各种审计行为信息的总称。政府审计行为是最重要的政府审计信息对象。政府审计信息可以根据行为主体、行为发生逻辑、行为性质、行为对象、行为发生时间进行分类。目前在信息公开实践中,政府审计信息边界模糊、体系不完整,影响了政府审计信息公开作用的发挥,因此需要准确把握政府审计信息的边界,建立科学审计信息内容体系,优化审计信息公开的内容结构。     

Belgium： Heart of Europe

With an area of about the size of China's Hainan Island, the country lies at the very heart of a major urban and economic corridor running from Liverpool(Unit- ed Kingdom) to Genoa(Italy)where 60% of Europe's purchasing power and 30% of EU consumers are centered. That is Belgium.
