The upcoming run-off for the Afghan presidential election and the newly declared summer offensive by the Taliban have not stopped Afghan President Hamid Karzai from visiting China again.

His four-day trip to China underscored Kabul's eagerness for support amid security challenges in the war-torn country, most notably the withdrawal of US and NATO troops by the end of the year and its ongoing presidential elections.

China will provide help within its reach to Afghanistan's reconstruction and jointly develop the Silk Road Economic Belt with the Central Asian country, President Xi Jinping told Karzai on Monday.
