UNCLOS allows freedom of navigation, no where does it explicit state it allows military surveillance. To equate the two as the same thing is an interpretation of some states. But other states consider uninvited military surveillance as non-peaceful activity. It's one thing if a P-8 flew over the reclamation enroute from point A to B. That's clearly freedom of navigation. But when merely circling around and having full sensor sweep, that's hardly just navigating.
International law and long-standing State practice recognizes the right of all nations to conduct surveillance and reconnaissance operations beyond the territorial sea of any nation. UNCLOS addresses intelligence collection in only one article—Article 19(2)(c), which prohibits ships transiting the territorial sea in innocent passage to engage in “any act aimed at collecting information to the prejudice of the defence or security of the coastal State.” A similar prohibition does not appear in Part V of the Convention regarding the EEZ or in Part VII regarding the high seas. Under generally accepted principles of international law (the Lotus Principle) , any act that is not specifically prohibited in a treaty is permitted. Consequently, intelligence collection in the EEZ is permitted under Article 58 and Article 87 of UNLOS as a high seas freedom.
China’s argument that intelligence collection activities are
per se a “threat or use of force” in violation of UNCLOS and the UN Charter is misplaced. UNCLOS Article 301 simply calls on States to “refrain from any threat or use of force against the territorial integrity or political independence of any State . . . .” Identical language is contained in Article 2(4) of the UN Charter. UNCLOS, moreover, makes a clear distinction between “threat or use of force” on the one hand, and other military activities (including intelligence collection) on the other. Article 19(2)(a) governing innocent passage mirrors the language of UNCLOS Article 301 and Article 2(4) of the UN Charter, prohibiting ships in innocent passage from engaging in “any threat or use of force against the sovereignty, territorial integrity or political independence of the coastal State . . . .” The remaining subparagraphs of Article 19(2) go on to restrict other military activities in the territorial sea, including the limitations on intelligence collection in subparagraph 2(c) discussed above.(Note that a similar restriction applies to ships engaged in transit passage and archipelagic sea lanes passage. Articles 39 and 54 call on ships exercising the right of transit passage and archipelagic sea lanes passage to “refrain from any threat or use of force against the sovereignty, territorial integrity or political independence of States bordering the strait [or the archipelagic State] . . . .” UNCLOS,
supra note 31, arts. 39 & 54.)
The separation of the two concepts—the use of force and intelligence collection—demonstrates that UNCLOS does not automatically equate one with the other. Intelligence collection, however else it may be characterized, is not necessarily a threat or use of force” under UNCLOS or the UN Charter.
This issue was considered by the UN Security Council following the shoot down of a U.S. U-2 spy plane by Soviet Air Defence Forces near Sverdlovsk in 1960.81 An effort by the Kremlin to have the UN body adopt a resolution that would have labelled all U.S. U-2 flights over Soviet territory as acts of aggression under the Charter was soundly defeated in the Security Council by a vote of 7 to 2 (with 2 abstentions), thereby confirming that peacetime intelligence collection is consistent with the UN Charter.( O.J. Lissitzyn,

Based on various provisions of UNCLOS, it is logical, to interpret the peaceful uses/purposes clauses as prohibiting only those activities which are not consistent with the UN Charter. It may be concluded accordingly that the peaceful purposes/uses clauses in Articles 88 and 301 do not prohibit all military activities [including intelligence collection] on the high seas and in EEZs, but only those that threaten or use force in a manner inconsistent with the UN Charter.

Article 87
2. These freedoms shall be exercised by all States with due regard for the interests of other States in their exercise of the freedom of the high seas, and also with due regard for the rights under this Convention with respect to activities in the Area.
Article 88
The high seas shall be reserved for peaceful purposes.
Presumably adequately addressed above.
Actually the retuning of a zone I suggested has very much a legal standing, Article 60. I never said a retuned zone is the equivalent of a territorial zone. But nonetheless, it is still a zone UNCLOS legally affords.
If my understanding is correct, if you read article 60 and the following sub clauses, the reference to artificial islands and the 500m limitation is about restricting any construction to no more than 500 m. As such, China's reclamation is already in contravention of UNCLOS.
The best way the US can respect the terms of UNCLOS is to ratify it. Or to put it in another way, why is the US not ratifying it if it so respects the terms of UNCLOS? Perhaps answering that is the best way of deciphering how much or how little the US position differs from UNCLOS.
The terms of the convention is well known and so are US actions. If US behaves in a manner inconsistent with UNCLOS they should be taken to task. The reason why the US has not ratified it is well known and I do not wish to offer any defence of its actions. You or anyone is free to criticize the current state in any way you want.
