My comment: I am confused.
(a) US years ago offered four Perry-classfrigates to Taiwan. After a couple of years, the Ma administration, having declined (for reasons unclear to me, but possibly due to budget constrait), agreed to buy two. See
Oliver Hazard Perry-class frigate
en.wikipedia.org/wiki/Oliver_Hazard_Perry-class_frigate
(In commission: 1977–Present; Completed: 71; Active: 11 (US Navy); section 4 Operator: "Republic of China (Taiwan) (Cheng Kung-class 成功級 巡防艦 [commissioned 1993- ]): Taiwanese-built [based on Perry]. Originally eight ships were equipped with eight Hsiung Feng II anti-ship missiles, now all but PFG-1103 [PFG: Patrol Frigate, Guided Missile] are carrying four HF-2 and four HF-3 supersonic AShM. The PFG-1103 Cheng Ho 鄭和號 will change the anti-ship mix upon their major overhaul. Seven out of eight ships added Bofors 40 mm/L70 guns for both surface and anti-air use. On November 5, 2012 Minister of Defense Kao 高 華柱 announced the US government will sell Taiwan two additional Perry-class frigates that are about to be retired from the U.S. Navy for a cost of US$240 million to be retrofitted and delivered in 2015.[16]")

Taiwan to Buy Perry-Class Frigates From US. Central News Agency (Taipei), Nov 5, 2012
("Taiwan will purchase two Oliver Hazard Perry-Class frigates from the United States in 2014")
(b) So, altogether will US sell four Perry-class frigates, or six?
