Today, state newspaper Neutral Turkmenistan carried a report claiming that the Guinness World Records body had awarded it two certificates for "largest horse head sculpture" and "largest aquatic sports park".
The newspaper's website published photos of what appeared to be two Guinness certificates recognising the achievements.
Both the horse head sculpture and the swimming pools are in the part of the capital, Ashgabat, where the 2017 Asian Indoor and Martial Arts Games are to be held in September.
The games, backed by the Olympic Council of Asia, have become a central theme in state propaganda and the government has spent heavily on sporting infrastructure despite an economic crisis linked to low prices for natural gas, a main export.

Guinness did not immediately respond to a request to confirm the records.
The certificate posted on Neutral Turkmenistan's website says there are 4,976.65 square metres of swimming pools in the Ashgabat Olympic complex, which combined constitute the world's "largest aquatic sports park".
Turkmenistan has claimed a number of obscure Guinness records under its strongman leader, President Gurbanguly Berdymukhamedov. In 2015 the country beat a record held by Google for the most people "singing in a round".
The choir of 4,166 people sang "Forward, Forward, My Dear Country Turkmenistan", supposedly composed by Berdymukhamedov, in a tightly choreographed show of state unity.
In 2013 Ashgabat claimed a record for having the highest density of white marble-clad buildings.
The year before it was recognised as having the world's largest ferris wheel in an enclosed space.
In 2015 the government unveiled a gold-leaf statue of Berdymukhamedov on horseback in Ashgabat, echoing an effigy to Niyazov in the centre of the capital that once rotated to follow the sun's movements
That statue has since been moved to the suburbs.
