Answer: A
Explanation: China–Pakistan relations began in 1951 when Pakistan was among the first countries to end official diplomatic relations with the Republic of China (on Taiwan) and recognize the People's Republic of China (PRC) regime on Mainland China. Since then, both countries have placed considerable importance on the maintenance of an extremely close and supportive special relationship[1][2][3] and the two countries have regularly exchanged high-level visits resulting in a variety of agreements. The PRC has provided economic, military, and technical assistance to Pakistan, and each country considers the other a close strategic ally.[4][5]
