On 6 July 1990, the Secretary-General received from the Government of the United Kingdom of Great Britain and Northern Ireland the following objection concerning the reservations made by Argentina:

The instrument contained a reservation rejecting the ratification of the Convention by the United Kingdom of Great Britain and Northern Ireland in respect of the Falkland Islands, South Georgia and the South Sandwich Islands and the British Antarctic Territory.

The Government of the United Kingdom of Great Britain and Northern Ireland wishes to state that they have no doubt as to British sovereignty over the Falkland Islands, South Georgia and the South Sandwich Islands and the British Antarctic Territory, and their consequent right to extend treaties to those territories. In respect of the British Antarctic Territory, the Government of the United Kingdom would draw attention to the provisions of Article IV of the Antarctic Treaty of 1 December 1959, to which both Argentina and the United Kingdom are parties. For the above reasons the Government of the United Kingdom rejects the Argentine reservation.

On 2 August 1990, the following objection was received by the Depositary from the Government of the United Kingdom of Great Britain and Northern Ireland:

"The Government of the United Kingdom of Great Britain and Northern Ireland have no doubt as to British

Sovereignty over the British Antarctic Territory. In this respect, the Government of the United Kingdom would draw attention to the provisions of Article IV of the Antarctic Treaty of 1 December 1959 to which both Chile and the United Kingdom are parties. For the above reasons, the Government of the United Kingdom rejects the Chile declaration."

On 27 January 1993, the UN Secretary-General received from the Government of the United Kingdom of Great Britain and Northern Ireland the following communication with respect to the declarations made by Mauritius upon the latterÆs accession to the Vienna Convention for the Protection of the Ozone Layer and the Montreal Protocol on Substances that Deplete the Ozone Layer:

"The Government of the United Kingdom of Great Britain and Northern Ireland have no doubt as to British sovereignty over the British Indian Ocean Territory and their consequent right to extend the application of the above Convention and Protocol to it. Accordingly the Government of the United Kingdom do not accept or regard as having any legal effect the declarations made by the Government of the Republic of Mauritius."

¹¹ On 18 July 1990, the following objection was received by the Depositary from the Government of Israel:

"The Government of the State of Israel has noted that the instrument of accession of Bahrain to the above-mentioned Convention and Protocol contains a declaration in respect of Israel. In view of the Government of the State of Israel such declaration, which is explicitly of a political character, is incompatible with the purposes and objectives of the Convention and Protocol and cannot in any way affect whatever obligations are binding upon Bahrain under general international law or under particular conventions. The Government of the State of Israel will, in so far as concerns the substance of the matter, adopt towards Bahrain an attitude of complete reciprocity."

Macao will, from that date, become a Special Administrative Region of the People's Republic of China and will enjoy a high degree of autonomy, except in foreign and defense affairs which are the responsibilities of the Central People's Government of the People's Republic of China.

In this connection, The Vienna Convention for the Protection of the Ozone layer, which the Government of the People's Republic of China deposited the instrument of accession on 11 September 1989, as well as the Montreal Protocol on Substances that Deplete the Ozone Layer of 16 September 1987 and the Amendment to the Montreal Protocol on Substances that Deplete the Ozone Layer of 29 June 1990 (hereinafter referred to as the "Convention, the Protocol and the Amendment"), will apply to the Macao Special Administrative Region with effect from 20 December 1999.
