Hong Kong media tycoon Jimmy Lai became the highest-profile person arrested under a new national security law on Monday, detained over suspected collusion with foreign forces as around 200 police searched the offices of his Apple Daily newspaper.

Mainland-born Lai, who was smuggled into Hong Kong on a fishing boat when he was a penniless 12-year-old, has been one of the most prominent democracy activists in the Chinese-ruled city and an ardent critic of Beijing.

AFP - Asian markets saw further losses on Thursday, with Tokyo hit by a weaker dollar and Hong Kong coming off a 12-day surge, as the rally that greeted 2018 gives way to profit-taking.

Hong Kong flag carrier Cathay Pacific will switch to biofuels made from landfill rubbish on select long haul flights, reports said Tuesday, in an effort to cut harmful emissions.

Cathay flights to Hong Kong from the US, where the new fuel is produced, will use a combination of conventional jet fuel and biofuels starting in 2019, the South China Morning Post reported.
