"The Year of India-China Friendship which both sides are celebrating in 2006 will be marked by a host of activities that we have agreed upon," Chinese Ambassador to India, Sun Yuxi told PTI.

Sun noted that Chinese Premier Wen Jiabao and Prime Minister Manmohan Singh jointly declared the year 2006 as the "Year of China-India Friendship' during Wen's successful visit to New Delhi in April, 2005.

It was the first time for the two countries to jointly launch such an activity in the 2,000-year history of friendly exchanges between China and India, he noted.

More than 50 activities will be held by both sides covering political, defence, economic and trade, culture and tourism, education, science and technology fields, Sun, who had recently launched the year-long activities in New Delhi at the Chinese Embassy premises, said.
