China's Foreign Ministry spokeswoman Hua Chunying said that her country followed up reports about banning Chinese submarines from docking Sri Lankan ports.
"I have noted relevant report," Chunying said during a daily press briefing.
"The Chinese vessel docked in Colombo, Sri Lanka for resupply when it sailed to the Gulf of Aden and the Somalian waters for escort mission," Chunying said.
"This activity is normal and transparent and approved by the Sri Lankan side in line with international common practice," she said.
"Based on my understanding, the Sri Lankan government holds a policy of supporting international anti-piracy campaign and welcoming the docking of vessels from any friendly country in its ports," she added.
