Statistics show that bilateral trade increased from some $1 billion in 2001 to nearly $19 billion in 2011.

Since 2001, Chinese companies have signed deals involving Turkish projects worth more than $10 billion. These include the Ankara-Istanbul high-speed railway, the biggest joint project.

During Premier Wen Jiabao's visit to Turkey in 2010, the two countries pledged to increase trade to $50 billion by 2015 and $100 billion by 2020.

According to Xinhua, during Xi's visit, a Chinese trade and investment promotion delegation consisting of more than 100 Chinese business leaders had signed deals worth about $4.3 billion.

The central banks of the two countries also inked a currency swap worth $1.58 billion as part of efforts by Beijing to promote the yuan internationally.

Turkey's Deputy Prime Minister Ali Babacan urged Chinese banks to do more business in Turkey, according to AFP.

"We want Chinese banks to open more branches in Turkey ... We also want Turkish banks to be more active in China," Babacan said.

Xi's visit was an important diplomatic initiative at the connecting point of Eurasia, Dong Manyuan, deputy director of the China Institute of International Studies, said.

Sharing similar views on regional security issues, including the peaceful resolution of the Iran nuclear issue and the fight against terrorism, Dong said, the two countries have "a promising future" in cooperation.

In addition to political and economic cooperation, Yao said cultural cooperation is also important for the two countries.

The countries have a long history of exchanges dating back to ancient times.

Turkey has designated 2012 as a Chinese Cultural Year and China will host a Turkish Cultural Year in 2013.
