Exporters from Pakistan have resumed supplying goods to Afghanistan after more than three weeks of uncertainty in Kabul.

After the Taliban seized control of the Afghan capital on Aug. 15, business was halted in major cities.

"For the last 20 days, I didn't place any order in Pakistan because of fear that the situation could be worse when the Taliban began capturing major cities," Afghan businessman Abdul Rahim QaziZai said.

"Now, I meet with my Pakistani counterparts and place orders for sugar and cooking oil," he said while going to Kabul via the Torkham border after spending three days in Peshawar, the capital city of Khyber Pakhtunkhwa province.

Hundreds of trucks lined the Khyber Pass, the main road connecting Pakistan and Afghanistan via the Torkham border, on Wednesday. They were full of food products waiting to cross the border toward eastern Jalalabad in Afghanistan.

Most drivers were waiting for three or four days near the border because of a lack of parking on the Afghan side. But the long queues provide a clear picture of economic activity resuming between the two countries.

"I am waiting here for the last three days and don't know when my turn will come to cross the border," said Nadir Shah, who was resting near his vehicle.

Shah’s vehicle was loaded with cement and was headed from Peshawar to Jalalabad.

Trucks were carrying cement, sugar, flour, cooking oil, salt, bananas, and other food items to Afghanistan.

Afghanistan is rich in resources like copper, gold, oil, natural gas, uranium, bauxite, coal, iron ore, rare earth, lithium, chromium, lead, zinc, gemstones, talc, sulfur, travertine, gypsum and marble which remain unexplored due to the 20-year war after the US invaded in 2001.

A Pakistani customs official at the Torkham border, who asked not to be named because he was not authorized to speak to the media, said trade has increased in the last few days.

"Since earlier August, we observed that most trucks were going back to Afghanistan empty to bring vegetables, fruits, and minerals but now they are taking goods from Pakistan as well," he said.

"We are facilitating these trucks and want to clear as soon as possible but due to lack of parking facilities on the other side of the border, these trucks are waiting here," he said.

The number of trucks crossing increased from 100 to 150 to 300 to 400, he said.

Interior Minister Sheikh Rashid Ahmed said on Aug. 19 that the situation along the border is "normal," and trade activities have been increased.

Figures from Pakistan's customs showed the number of trucks moving across all border points reached 1,123 on Aug. 17 from 475 on Aug. 15, the Dawn newspaper reported.

The trade volume between Pakistan and Afghanistan dropped during the last decade from $1.5 - $2 billion to $754 million in 2020, due to tense relations between former Kabul governments and Islamabad, trading accusations of providing a haven to terrorists.

But it slightly increased in the current April - July period to $869 million after Prime Minster Prime Minister Imran Khan visited Kabul last November, according to the Commerce Ministry data.
