Before his departure Wen delivered a speech at the Pakistani parliament here on Sunday, calling on the two countries to advance their strategic partnership of cooperation and join hands to shape the future.
""To cement and advance the all-weather strategic partnership of cooperation between China and Pakistan is our common strategic choice,"" he said.
Addressing Pakistani lawmakers, Wen highlighted the true friendship between China and Pakistan, saying that the two neighboring countries are ""brothers forever.""
Recalling Pakistan's consistent and full support to China in the past at some crucial junctures and on various issues, including issues concerning Taiwan, Tibet and Xinjiang, Wen said that China received valuable help from Pakistan.
On trade and finance, Wen said China backs Pakistan's endeavor to develop itself through expanded international trade and investment cooperation.
Wen oversaw signing of 22 agreements for cooperation in agriculture, food, machinery, and space and upper atmosphere research on Saturday. Few details of the agreements have been released. Both sides also agreed on targeting an increase in bilateral trade to $18b by 2015, from $7b in 2009.

""China welcomes Pakistan's effort to capitalize on the preferential terms in the bilateral FTA to expand exports to China,"" Xinhua quoted Wen’s speech in the parliament on Sunday.
Wen also said China may explore the possibility of a currency swap agreement with Pakistan.
China has decided to provide 500 university scholarships to Pakistan in the next three years, and 100 Pakistani high school students will be invited to participate in the Chinese Bridge Summer Camp in China, Wen said.
China and Pakistan officially established diplomatic ties in 1951 and the two sides will celebrate the Year of China-Pakistan Friendship in 2011.
