BEIJING -- China and the United Nations Economic and Social Commission for Asia and the Pacific (UNESCAP) have signed a cooperation document to promote the Belt and Road Initiative construction.

The letter of intent was signed by Foreign Minister Wang Yi and visiting UNESCAP Executive Secretary Shamshad Akhtar in Beijing on Monday, said Foreign Ministry spokesman Lu Kang on Tuesday.

According to the document, the two sides will jointly promote regional connectivity and the implementation of the Belt and Road Initiative. The two sides will make specific action plans, and encourage relevant countries to synchronize their development strategies with the initiative, Lu said.

He noted that the letter of intent is the first document signed between China and an international organization on boosting cooperation under the Belt and Road Initiative, though China has signed cooperation deals with more than 30 countries in this regard.
