Chinese Premier Wen Jiabao arrived in Yangon Wednesday, kicking off a two-day official visit to Myanmar, which is the last leg of his current four-nation Asian tour.

During the visit, Wen will visit the No.1 Middle School of Yangon and the Shwedagon Pagoda on Wednesday and then travel to the capital of Naypyitaw.

In Naypyitaw, Wen will meet with Myanmar's top leader, Senior-General Than Shwe, Prime Minister U Thein Sein and other government officials.

China and Myanmar will sign a package of documents aimed at strengthening economic and trade cooperation, according to Chinese ambassador to Myanmar, Ye Dabo.

Ye said China was now Myanmar's third largest trading partner and investor. In 2009, bilateral trade totaled 2.907 billion U.S. dollars. Up to January 2010, China's investment in Myanmar amounted to 1.848 billion dollars, accounting for 11.5 percent of Myanmar's total foreign investment.

In recent years, the two sides had expanded cooperation in hydropower, energy, mining, communications, fishery, manufacturing and infrastructure, and there had been frequent exchanges in culture, news and sports, Ye said.

Before flying to Myanmar, Wen visited South Korea, Japan and Mongolia. In South Korea, he also attended the Third Trilateral Meeting of leaders of China, South Korea and Japan.
