After years of separation from his wife in mainland China, Hong Kong resident Cheung Seng-bun made sure to be among the first in line following the reopening Sunday of border crossing points.
Those crossing between Hong Kong and mainland China, however, are still required to show a negative COVID-19 test taken within the last 48 hours — a measure China has protested when imposed by other countries.
Hong Kong media reports said around 300,000 travel bookings from the city to mainland China have already been made, with a daily quota of 60,000.
"I've been under isolated quarantine for six times in different cities (in mainland China)," said Ivan Tang, a Hong Kong business traveler.
Meanwhile, more foreign governments are imposing testing requirements on travelers from China — most recently Germany, Sweden and Portugal.
