25-year old man has been charged in connection with smuggling £130,000 worth of cannabis.
Guang Xu, with an address at Beech Heights in south Belfast, was remanded in custody.
Police told Belfast Magistrate's Court they feared he could flee the country and was also at a high risk of re-offending.
The charges relate to the delivery of a cannabis package to Mr Xu's flat in the Annadale area of Belfast last Thursday.
A 26-year-old man has been arrested on Saturday following the seizure. Another man, aged 22, arrested in the flat, has been released on bail.
Police said they believed Mr Xu had been involved in up to six similar transactions currently under investigation.
He is due to appear again on 25 July.
