Kathmandu: Nepalese Deputy Prime Minister on Sunday embarked on a key visit to China to discuss bilateral security cooperation and facilitate a future tour of Chinese Premier Wen Jiaboa.

Bijaya Kumar Gachhadar, who is also Nepal's Home Minister is also accompanied by some high government delegation and senior security officials during the five-day visit.

"The DPM is expected to meet Chinese Premier Wen Jiabao and his Chinese counterpart Meng Jianzhu and discuss bilateral security cooperation and make arrangements for Chinese PM's visit," sources at the Home Ministry said.

The visit of the President of Madhesi Peoples Rights Forum (Democratic) is expected to pave the way for Wen's Nepal visit that was postponed earlier this month, according to political analysts.

Chinese Premier Wen's three-day visit from December 20 was postponed apparently due to security concerns.

However, the Chinese side informed that it was postponed due to urgent economic matters at home.

Media reports here suggest that the Chinese side was concerned over growing anti-Beijing activities by Tibetan refugees in Nepal.

Now Gachhada has embarked on the China visit in an attempt to address Beijing's concerns, according to media reports.

It has been widely speculated here that Wen's visit would take place once the Chinese side is fully convinced of the security arrangements in Kathmandu.

"Gachhadar's meeting with Chinese Foreign Minister Meng will be crucial in deciding Wen's visit to Nepal," reported The Kathmandu Post.
