LONDON, March 29 (Reuters) -Perenco issued tenders for May-loading crude while differentials for West African crude remained under pressure from slow sales to China and Europe.

* Indonesia's Pertamina closed a tender for June-arriving crude due, but results were slow to emerge.

* French oil company Perenco issued sell tenders for three varieties of crude oil due to close later this week - Cameroonian Kole, Gabonese Mandji and Rabi Light.

* French refinery strikes continued to squeeze demand for West African and especially Nigerian crude, where almost three dozen April-loading cargoes remain unsold.

* Finalized Angolan export plans for May remained steady at 33 cargoes, a relatively low volume.

* Offers for light sweet Nigerian Qua Iboe and Bonny Light crude stood at about dated Brent plus $1.60 a barrel, traders said, down by about 40 cents since the end of last week.
