Hong Kong has prohibited Financial Times' Asia news editor Victor Mallet from entering the territory.
Mallet who tried to enter as a tourist on Thursday, November 8, 2018 was immediately dismissed after his questioning by immigration officials.
The denial comes just a month after the territory declined to renew his work visa without any further explanation.
In August, Mallet hosted an event at Hong Kong's Foreign Correspondent Club (FCC) that featured an independence activist. The event drew anger from the officials.
China's foreign ministry had urged the club to cancel the event featuring activist Andy Chan, founder of the Hong Kong National Party.
However, British citizens are usually allowed entry to Hong Kong for 180 days without a visa, according to the tourist board.
The FCC has recapped its request for an explanation from Hong Kong's top official Carrie Lam about the original visa denial.
Under the so-called "one country, two systems" formula, Hong Kong enjoys a high degree of autonomy and certain freedoms not available in China.
However, on the same day Hong Kong denied Mallet's entry, Chinese author Ma Jian announced the cancellation of his events in the Hong Kong International Literary Festival being held at the government-backed Tai Kwun arts complex.
Organizers will now have to find an alternative venue, he said, although it is unclear whether the events will push thru at all.
In later tweets, as the writer boarded a plane bound for Hong Kong, he thoroughly expressed his concerns that he might not be allowed through immigration.
"It would have been easy not to go, to avoid difficult questions," he wrote. "But more and more it seems to me that in literature, there is nowhere to hide."
These latest moves come after the authorities banned the small Hong Kong National Party that advocates for the territory's independence.
It marked the first time the territory banned a political party since it was returned to China from the UK in 1997.
