The Telegraph reports that the Egyptian government is pressing its advantage to get some if its antiquities returned:

The French culture ministry has decided to return the 3,200-year-old frescoes, which disappeared in the 1980s, Egypt said, and were acquired by the Louvre in Paris in 2000 and 2003. [… Zahi Hawass, head of Egypt’s supreme council of antiquities] told The Daily Telegraph that the return of the painted fragments would “warn every museum not to buy stolen artefacts”. He now wants the British Museum to lend the Rosetta Stone to Cairo. The artefact, dating from 196BC, carries inscriptions in Greek and Egyptian that first enabled hieroglyphics to be deciphered. “I am not asking for all the objects in the British Museum to come back, only for the unique objects to come back to Egypt,” he said.
