Malaysia's state fund 1MDB said that it had been served today with a request for arbitration by Abu Dhabi's International Petroleum Investment  Company (IPIC) and Aabar Investments PJS, in relation to its  ongoing dispute with IPIC. 

1Malaysia Development Berhad (1MDB) appointed Weil Gotshal & Manges to represent it in the dispute and will file a response to the request before the deadline of 11 July, it said in a statement.

IPIC has asked a London court to arbitrate in the dispute with 1MDB, in which it is claiming about US$6.5 billion.
