Pakistan has suspended all trade with India and closed its airspace and land border. The measures follow the imposition of sanctions imposed by India after an attack in Indian-administered Kashmir that killed 26 people on Tuesday.
The last six months saw 520 port calls of vessels between Pakistan and India, according to data from maritime analytics firm Windward.
The two neighbours do not have a huge trading relationship. In the last full financial year, Pakistan imported Indian goods worth $1.2bn, while India imported goods worth only $3m from Pakistan.
