The Chinese navy on Saturday successfully escorted an Indian oil tanker carrying 31 Indian crew members to a designated sea area in the Gulf of Aden and received a thank-you note from the tanker's captain, the Global Times learned on Monday. The escort came amid the recently strained diplomatic ties between China and India on the border dispute.
