UNCTAD's flagship publication, World Investment Report 2012, released in July, predicted that global FDI will grow from $1.6 trillion in 2012 to $1.8 trillion in 2013 and $1.9 trillion in 2014.
Eddie Chen, vice-president and chief representative in China of Invest Sweden, said China has a "good opportunity" to increase its influence in drafting global investment rules.
"The next decade of global investment will see more players from emerging economies, with China being the leading one," Chen said.
Chen said China should join forces with other emerging economies in promoting global investment rules.
Liu Yanzhou, managing director of Beijing Ring New Venture Capital Management Co Ltd, called for a coordination mechanism to safeguard the participation of small and medium-sized enterprises, the major players in economic innovation, in global investment.
Sun also called on the Chinese government to improve the investment environment.
He said that the government should cut red tape, devote more efforts to protecting intellectual property rights and resolve problems concerning national treatment of foreign companies in China.
"Moreover, more common views should be reached between China and the West on regulating government and corporate behavior," added Sun.
Wang Zhile, president of Beijing New Century Academy on Transnational Corporations, said that the promotion of global investment rules would not only boost mutual investment but also facilitate Chinese companies tapping into international markets.
Wang said that the double-digit growth in sales and profits of world's top 500 transnational companies in 2010 and 2011, if continued in the next two years, will lift the sluggish world economy.
